Choosing the right spark plugs for your Hyundai Veloster can help restore smoother starts, steadier idle, cleaner acceleration, and better day-to-day drivability when worn plugs are the cause. For first-generation 2012–2017 Velosters, the key step is identifying the exact engine before choosing a plug. Naturally aspirated and Turbo 1.6L models can require different spark plug part numbers, heat ranges, and gaps.
This guide compares seven spark plug options sold for Hyundai Veloster or related Hyundai/Kia 1.6L applications, with the strongest fitment support centered on the naturally aspirated 1.6L. Turbo owners should not assume these plugs fit. Confirm your model year, engine/aspiration, OEM or manufacturer cross-reference, and required gap in the owner’s manual or a current manufacturer fitment catalog before ordering.

Quick Verdict
Best OEM-style route for a naturally aspirated 2012–2017 Veloster: start with the NGK Laser Iridium listing and verify the exact part number against your car. Best performance-oriented NGK alternative: NGK Iridium IX when the current listing matches the required cross-reference. Best budget alternative: Champion Copper Plus for a compatible naturally aspirated 1.6L when you accept a more basic plug design and potentially shorter replacement intervals. DENSO and the aftermarket four-packs can also work for the applications stated by their listings, but they need especially careful fitment confirmation.
Fitment Note Before You Buy
Do not shop by “1.6L Veloster” alone. First-generation naturally aspirated and Turbo engines use different spark plug specifications. Common naturally aspirated references include NGK SILZKR6B10E/93815 and LZKR6AIX/92873, but the correct choice still depends on the exact year and engine. Turbo models can require different plugs and a different gap. Match the current plug or OEM specification, confirm the manufacturer’s latest fitment data, and never force a plug that does not match the required thread, reach, heat range, or gap.

How We Picked These Spark Plugs
We prioritized fitment evidence first, then plug construction, manufacturer or seller cross-references, gap information, brand recognition, installation practicality, and value. Because the first-generation Veloster was sold with both naturally aspirated and Turbo 1.6L engines, a listing that only says “1.6L Veloster” is not enough by itself.
We also separated OEM-style iridium choices from performance-oriented iridium and lower-cost copper alternatives. Iridium and platinum-style plugs generally appeal to drivers who want longer service intervals, while copper alternatives can make sense for budget maintenance when the manufacturer catalog confirms the application.
Before You Buy Checklist
- Confirm your exact Veloster model year and whether the 1.6L is naturally aspirated or Turbo.
- Match the OEM part number or a manufacturer-approved cross-reference, not just the vehicle name.
- Confirm the required heat range, thread/reach, and gap from a current manufacturer catalog or service information.
- Replace all four plugs together unless a qualified diagnosis calls for a different repair.
- Work on a cool engine, start each plug by hand, and use the specified torque to reduce thread-damage risk.
4 Pc Denso Iridium Power Spark Plugs
If you drive a 2012–2014 Hyundai Veloster and the current listing matches your exact engine and plug specification, these DENSO Iridium Power plugs are a premium aftermarket option. Iridium construction is designed to maintain a small, durable firing tip, but that does not make every DENSO plug interchangeable across naturally aspirated and Turbo engines.
Choose this set only after confirming the exact DENSO part number, heat range, gap, and engine application. The listing’s broad year-and-engine wording is not enough to prove Turbo compatibility, so owners should cross-check a current DENSO catalog or their OEM plug before ordering.
Listing & Fitment Notes
The source listing identifies this as a DENSO Iridium Power four-pack for 2012–2014 Veloster 1.6L applications, but the exact plug part number is not stated in the article. Because first-generation Veloster engines are not all plug-interchangeable, verify the current DENSO catalog match before purchase.
The legacy sentiment graphic below is retained from the source article, but its underlying review sample was not independently verified here. Use current verified listing details and recent customer reviews only as secondary buying signals.
🔧 Fitment note
Verify the exact DENSO part number, engine type, heat range, and gap before installation.
🛠️ Install note
Start each plug by hand and use the vehicle or plug maker’s torque specification rather than relying on feel.
Who Should Buy This
Best for 2012–2014 owners who can confirm the exact DENSO application and want an iridium aftermarket replacement.
What It Can Address
Worn plugs can contribute to rough idle, weak starts, misfires, and uneven throttle response. Replacing them can help when diagnosis confirms the plugs are the cause.
Key Benefits
- Iridium-style design for a focused, consistent spark
- Listed for Hyundai Veloster 1.6L 2012–2014 fitment
- Good choice for a premium maintenance refresh
- Can help restore smoother idle and cleaner starts when old plugs are worn

Iridium Platinum Spark Plugs (Pack of 4)
If you want an aftermarket plug that combines an iridium center electrode with a platinum-style ground electrode, this AMICAREP four-pack is a cross-reference-driven option. The listing associates it with 92873/LZKR6AIX-style applications, so it is more relevant to naturally aspirated Veloster fitment than to Turbo models.
The main caution is the broad Hyundai/Kia compatibility language. Treat the listing as a starting point, not proof of fit. Confirm your exact year, engine, OEM plug reference, gap, and heat range before ordering.
Listing & Fitment Notes
The listing uses 92873/LZKR6AIX as a replacement reference and describes broad Hyundai/Kia 1.6L/1.8L compatibility. That can help with cross-shopping, but a shared engine size does not guarantee interchangeability across every model or engine variant.
The legacy sentiment graphic below is retained from the source article, but its underlying review sample was not independently verified here.
🔧 Fitment note
Use the OEM plug or a current manufacturer catalog to confirm that 92873/LZKR6AIX is valid for your exact naturally aspirated application.
🛠️ Install note
Verify the required gap and torque specification before installation; do not assume every aftermarket set arrives at the correct final gap for your vehicle.
Who Should Buy This
Best for naturally aspirated Veloster owners who can confirm the 92873/LZKR6AIX cross-reference and want a lower-cost mixed-metal aftermarket set.
What It Can Address
Fresh plugs can help with rough idle, misfires, or weak starts when worn or fouled plugs are confirmed as the cause. Carbon or drivability problems may have other causes and should be diagnosed separately.
Key Benefits
- Iridium and platinum-style material combination
- Nickel-plated shell listed for corrosion resistance
- Cross-reference support for 92873 and LZKR6AIX-style applications
- Useful for maintenance refreshes when fitment is confirmed
- Pack of four covers a full 4-cylinder replacement

Champion Copper Plus Spark Plugs (Pack of 4)
If you want a lower-cost alternative for a compatible naturally aspirated 1.6L Veloster, Champion Copper Plus is the simplest option in this roundup. Current catalog data supports RER8MC/Copper Plus for naturally aspirated first-generation Veloster applications at a 0.040-inch catalog gap, but Turbo owners should not use that as proof of fit.
The tradeoff is service life and specification confidence. Copper-style plugs can be economical, but the Veloster was commonly equipped with long-life iridium-style plugs. Choose this option only when the current Champion catalog or another authoritative fitment source confirms it for your exact engine.
Listing & Fitment Notes
Champion catalog references support RER8MC/Copper Plus for naturally aspirated 1.6L Veloster applications. The article’s Amazon listing covers 2012–2017, but engine aspiration still needs to be checked before purchase.
The legacy sentiment graphic below is retained from the source article, but its underlying review sample was not independently verified here.
🔧 Fitment note
Confirm naturally aspirated 1.6L fitment and the current Champion specification before ordering.
💰 Buying note
This is the budget-focused choice when a catalog confirms it; choose iridium instead if longer service intervals are your priority.
Who Should Buy This
Best for budget-focused owners of a naturally aspirated 1.6L Veloster when the current Champion catalog confirms fitment.
What It Can Address
Can help resolve rough idle, hard starts, or light misfire symptoms when worn plugs are diagnosed as the cause.
Key Benefits
- Listed for Hyundai Veloster 1.6L L4 2012–2017
- Copper core design for simple, reliable ignition
- Recognizable Champion replacement option
- Good choice for budget maintenance
- Pack of four covers all cylinders

A-NAFTULY Iridium Spark Plugs (4 Pack)
These A-NAFTULY iridium plugs are sold as a four-pack for naturally aspirated Hyundai Veloster and related Hyundai/Kia applications, using references including 92873/LZKR6AIX and 93815/SILZKR6B10E. That makes them easy to compare by part number, but it also creates a reason to verify carefully because those references are not a substitute for checking the exact engine application.
The appeal is convenience and price positioning rather than proven OEM equivalence. Confirm the exact engine, current cross-reference, heat range, and final gap before installation, especially because aftermarket listing data can be inconsistent.
Listing & Fitment Notes
Current third-party listing data for this ASIN identifies naturally aspirated Veloster fitment and references 92873/LZKR6AIX plus 93815/SILZKR6B10E. Because seller pages can show inconsistent gap formatting, use the plug maker or vehicle specification as the final authority.
The legacy sentiment graphic below is retained from the source article, but its underlying review sample was not independently verified here.
🔧 Fitment note
Use the current manufacturer or seller fitment data only after confirming your Veloster is the naturally aspirated application covered by the cross-reference.
⚠️ Buying note
Do not assume a stated pre-gap is correct for your car; verify the required gap without damaging the fine-wire electrode.
Who Should Buy This
Best for value-focused naturally aspirated Veloster owners who are comfortable verifying aftermarket part-number cross-references before installation.
What It Can Address
May help with rough idle, intermittent misfires, weak cold starts, or uneven low-speed running when worn plugs are confirmed as the cause.
Key Benefits
- Iridium-style replacement set
- Cross-references 92873, LZKR6AIX, 93815, and SILZKR6B10E
- Listed for Veloster and related Hyundai/Kia 1.6L applications
- Full four-pack for a complete 4-cylinder replacement
- Useful for shoppers who want a simple tune-up set

IFATRUNK Iridium Spark Plugs (4 Pack)
The IFATRUNK set is a value-oriented iridium four-pack sold for 2012–2017 Veloster and related Hyundai/Kia applications. Current third-party listing data ties it to 92873/LZKR6AIX-style fitment, which is most relevant to naturally aspirated applications rather than Turbo models.
Choose it for price and four-plug convenience, not because it has stronger fitment authority than an OEM or major-brand catalog. Verify the exact engine, cross-reference, heat range, and required gap before installation.
Listing & Fitment Notes
The listing references 92873/LZKR6AIX and sells the set as a vehicle-specific replacement for several Hyundai/Kia models. That is useful for shortlisting, but the exact Veloster engine still needs to be verified before purchase.
The legacy sentiment graphic below is retained from the source article, but its underlying review sample was not independently verified here.
🔧 Fitment note
Cross-check 92873/LZKR6AIX against your existing plug or a current manufacturer fitment source.
💰 Buying note
Consider this set when value matters more than brand recognition and you are willing to verify the application carefully.
Who Should Buy This
Best for value-focused naturally aspirated Veloster owners who can verify the 92873/LZKR6AIX cross-reference.
What It Can Address
Can help with rough idle, intermittent misfires, or cold-start issues when worn, fouled, or incorrectly gapped plugs are the confirmed cause.
Key Benefits
- Iridium-style central electrode listed for focused spark delivery
- References 92873 and LZKR6AIX replacement numbers
- Seller listing provides a gap specification; confirm it against current vehicle/manufacturer data
- Vehicle-specific fitment language for Veloster 2012–2017
- Set of four covers a full 4-cylinder replacement

NGK Laser Iridium Spark Plugs (4 pc)
If you own a naturally aspirated first-generation Veloster, NGK Laser Iridium is the strongest OEM-style route in this roundup when the current listing matches your exact plug reference. NGK catalog data identifies SILZKR6B10E/93815 as a naturally aspirated 1.6L application, which is a more useful fitment check than engine size alone.
Choose this set if you prioritize an OEM-style iridium design and brand recognition. Turbo owners need a different fitment check, and every buyer should confirm the exact part number and required gap for the vehicle before installation.
Listing & Fitment Notes
NGK’s application data separates naturally aspirated and Turbo Veloster plug specifications. For the naturally aspirated 1.6L, SILZKR6B10E/93815 is a recognized Laser Iridium reference. Confirm that the Amazon set you receive matches the exact number required by your vehicle.
The legacy sentiment graphic below is retained from the source article, but its underlying review sample was not independently verified here.
🔧 Fitment note
Verify the exact NGK stock/part number against the vehicle application; do not use “2012–2017 1.6L” as the only fitment test.
🛠️ Install note
Check the required gap and torque specification before installation even when a plug is sold as pre-gapped.
Who Should Buy This
Best for naturally aspirated 2012–2017 Veloster owners who want an OEM-style NGK iridium option and can confirm the exact part number.
What It Can Address
Can help with rough idle, light misfires, weak starts, or inconsistent throttle response when worn plugs are diagnosed as the cause.

- Listed for Hyundai Veloster 1.6L L4 2012–2017

NGK Iridium IX Spark Plugs (4 pc)
The NGK Iridium IX set is a strong performance-oriented alternative for naturally aspirated Veloster applications when the required reference is LZKR6AIX/92873. That reference is cataloged for naturally aspirated 1.6L fitment, so it should not be treated as a universal first-generation Veloster plug.
Compared with the copper option, Iridium IX uses a fine-wire iridium firing tip and is positioned as a premium aftermarket plug. It is not the same thing as claiming OEM equivalence. Verify the exact part number, heat range, gap, and engine application before installation.
Listing & Fitment Notes
NGK 92873/LZKR6AIX is cataloged as an Iridium IX option for naturally aspirated 1.6L Veloster applications. Current retailer data can show slightly different pre-gap formatting, so use the vehicle/manufacturer specification rather than assuming the seller’s displayed gap is the final authority.
The legacy sentiment graphic below is retained from the source article, but its underlying review sample was not independently verified here.
🔧 Fitment note
Use 92873/LZKR6AIX only when a current application source confirms it for your exact naturally aspirated Veloster.
🛠️ Install note
Start plugs by hand and tighten to the correct specification to reduce the risk of cross-threading or over-tightening.
Who Should Buy This
Best for naturally aspirated Veloster owners who want an NGK Iridium IX aftermarket option and can confirm 92873/LZKR6AIX fitment.
What It Can Address
Can help smooth rough idle, reduce misfires, or improve cold-start behavior when worn spark plugs are the underlying problem.

- Use the current NGK/vehicle gap specification for your exact application
- Listed for Hyundai Veloster 1.6L L4 2012–2017

FAQ
How Do I Choose The Right Spark Plugs For My Hyundai Veloster?
Start by confirming your model year, whether the 1.6L engine is naturally aspirated or Turbo, the OEM plug part number, and the required heat range and gap. Many products in this guide are sold for 2012–2017 Veloster applications, but that broad wording does not mean one plug fits every first-generation Veloster.
Once the exact application is confirmed, choose based on your priority. OEM-style iridium is the safest general direction for buyers who want long service life, Iridium IX is a performance-oriented aftermarket option when the cross-reference matches, and copper is the budget alternative when a current catalog confirms it.
Do These Spark Plugs Fit The Hyundai Veloster Turbo?
Do not assume they do. The Turbo 1.6L uses different spark plug specifications from the naturally aspirated 1.6L in multiple first-generation model years. This roundup is strongest for naturally aspirated fitment. Turbo owners should match the exact OEM plug or a current manufacturer catalog entry for their year before buying.
What Are The Signs My Spark Plugs Need Replacing?
Common signs include rough idle, hard starts, engine hesitation, reduced fuel economy, misfires, and a check engine light related to ignition or cylinder misfire codes. If the plugs show heavy carbon deposits, worn electrodes, oil fouling, or the gap has changed, replacement may be due.
Because similar symptoms can also come from ignition coils, fuel delivery, vacuum leaks, or sensors, diagnose the issue before assuming spark plugs are the only problem.
Can You Install These Spark Plugs Yourself?
Yes, if you are comfortable working on your Veloster’s ignition system. Work on a cool engine, remove one plug at a time, start the new plug by hand, and use a torque wrench when possible. Do not over-tighten, and do not force a plug that does not thread smoothly.
Check the gap before installation even if the listing says the plug is pre-gapped. Avoid anti-seize unless the spark plug maker specifically allows it, because many modern plugs already have plated threads.
Are Iridium Spark Plugs Better Than Copper For A Veloster?
For many naturally aspirated first-generation Velosters, an OEM-style iridium plug is the more conservative long-service choice. Copper alternatives can still be valid when a current catalog lists them for the exact engine, but they are generally chosen for lower upfront cost rather than maximum service interval.
Should You Replace All Four Spark Plugs At Once?
For routine maintenance, replacing all four plugs as a matched set is usually the cleanest approach on the four-cylinder engine. If you are diagnosing a misfire or another fault, follow the repair procedure and confirm that coils, injectors, wiring, compression, or other causes are not being mistaken for a spark plug problem.
Drivers’ Top Picks
Fitment comes first and material comes second. For a naturally aspirated 2012–2017 Veloster, NGK Laser Iridium is the strongest OEM-style starting point when the exact part number matches, while NGK Iridium IX is a performance-oriented alternative for the correct 92873/LZKR6AIX application. Champion Copper Plus is the budget alternative when the current catalog confirms RER8MC. DENSO, IFATRUNK, A-NAFTULY, and AMICAREP remain reasonable shortlist options only after their exact application is verified. Turbo owners should use a Turbo-specific plug lookup rather than relying on this ranking.
Wrapping Up
Pick spark plugs by exact engine application, not by “Hyundai Veloster 1.6L” alone. For naturally aspirated first-generation cars, OEM-style iridium is the safest general starting point, while Iridium IX, copper, and other aftermarket sets can make sense when their part-number cross-reference is confirmed.
If you own a Turbo, use the Turbo-specific OEM or manufacturer application before buying. For every engine, confirm the part number, heat range, gap, and torque specification before installation.
