If you own a Hyundai Santa Fe or Santa Fe Sport, the correct spark plugs can help restore normal starting, idle quality, and combustion when worn plugs are causing problems. Spark plugs may look simple, but the replacement needs to match your exact model year, engine, thread dimensions, heat range, part-number specification, and required gap.

This guide compares four spark plug sets for select 2001–2018 Hyundai Santa Fe and Santa Fe Sport applications, including 2.0L and 2.4L four-cylinder Santa Fe Sport engines and several older V6 applications. It is not a universal fitment guide for every Santa Fe generation. Before ordering, confirm your exact engine and plug specification with your owner’s manual, service information, Amazon vehicle checker, and the part number shown in the product listing.

How We Chose These Hyundai Santa Fe Spark Plugs

Fitment came first. A premium electrode material cannot make up for the wrong thread, heat range, reach, gap, or engine application. We therefore focused on the vehicle and engine information attached to each listing rather than treating these plugs as universal upgrades.

• Vehicle and engine compatibility: Each remaining product has a stated Santa Fe or Santa Fe Sport application.
• Pack size: Four-piece sets are matched with four-cylinder applications, while the older V6 recommendations contain six plugs.
• Part-number clarity: We prioritize listings that provide reference numbers buyers can compare with their existing plugs or service information.
• Electrode design: The roundup includes iridium, double-iridium-style, and Platinum TT options without assuming that one material fits every engine.
• Buyer usefulness: Recommendations are grouped by engine application instead of using a misleading universal “best overall” ranking.

Before You Buy Hyundai Santa Fe Spark Plugs

• Find your exact engine: Model year alone is not enough. Confirm displacement and engine configuration.
• Match the plug number: Compare the OEM number, service number, or approved cross-reference with reliable service information.
• Buy the correct quantity: A four-cylinder needs four plugs for a full change; a V6 needs six.
• Verify the gap: Do not assume every plug advertised for a Santa Fe uses the same gap specification.
• Check torque specifications: Incorrect tightening can damage the plug or cylinder-head threads.
• Handle fine-wire electrodes carefully: Do not aggressively bend or pry against an iridium center electrode when checking gap.
• Diagnose persistent misfires: Spark plugs are only one possible cause. Ignition coils, wiring, injectors, sensors, compression problems, or air/fuel faults can produce similar symptoms.

A-Premium Iridium Platinum Spark Plugs (4-Pack)

The A-Premium Iridium Platinum Spark Plugs are the clearest option in this roundup for a listed 2013–2018 Hyundai Santa Fe Sport 2.0L. The product is sold as a four-piece set and references SILZKR8E9G-style fitment, making the pack quantity appropriate for the listed four-cylinder application.

The listing specifies an iridium-tip/platinum-core design, 12 mm thread diameter, and a listed 0.036-inch gap. Those specifications are useful cross-checks, but they should not replace the factory specification for your exact vehicle. When worn plugs are responsible for rough starting or uneven combustion, installing the correct replacements can help restore normal ignition behavior.

Best For

Choose this set if you have a listed 2013–2018 Santa Fe Sport 2.0L and your service information matches the product’s reference specification.

A-Premium Double Iridium Spark Plugs

The A-Premium Double Iridium Spark Plugs are a more precise choice for listed 2013–2015 Hyundai Santa Fe Sport 2.4L applications. The product references DILKR6C11/93199-style fitment and comes as a four-piece set, matching the plug count needed for the listed four-cylinder engine.

The listing identifies a 12 mm thread diameter and a 0.044-inch gap. Use those details as verification points rather than assuming all 2.4L Hyundai engines use the same plug. This product makes the most sense as a maintenance replacement when its specifications match the plugs required by your engine.

6 pc DENSO Platinum TT Spark Plugs

The 6 pc DENSO Platinum TT Spark Plugs are the strongest recognizable-brand option in this group for select older Hyundai Santa Fe V6 applications. The kit is marketed for 2001–2009 Santa Fe 2.7L, 3.3L, and 3.5L V6 applications, with exact engine coverage varying by year.

The six-piece quantity is a major advantage for V6 maintenance because you can purchase the full plug count in one set. The listing also identifies a 0.040-inch gap for its stated applications. Even with the detailed vehicle coverage, verify your exact year, engine, and required DENSO specification before ordering.

Pick this set if you have a compatible older Santa Fe V6 and prefer a six-piece set using DENSO Platinum TT plugs.

Fitment and Install Notes

A-NAFTULY Iridium Spark Plugs 6 Pack 5464 BKR5EIX-11

This six-pack is an alternative for owners of select older Santa Fe V6 applications whose service information calls for a BKR5EIX-11/5464-style plug. The product listing markets the set for 2001–2009 Santa Fe 2.7L, 3.3L, and 3.5L applications and identifies A-NAFTULY as the brand.

The six-plug quantity is appropriate for a complete compatible V6 service. However, the “5464” reference should not be mistaken for proof that these are NGK-branded plugs. Treat the cross-reference as a fitment clue and verify thread, reach, heat range, gap, and approved part number for your exact engine before ordering.

Best For

Consider this set if you need six iridium-style plugs for a compatible older Santa Fe V6 and your service information confirms BKR5EIX-11-style fitment.

Fitment and Install Notes

Why You’ll Like Them

• Six-piece pack suits a full compatible V6 plug change
• Iridium-style construction provides an alternative to the Platinum TT set
• BKR5EIX-11-style reference gives you a specific number to verify
• Useful when your older Santa Fe’s service information matches the listing

Buy If

You need six plugs for a compatible older Santa Fe V6 and have independently confirmed the BKR5EIX-11-style specification.

Skip If

You want genuine NGK-branded 5464 plugs specifically, your vehicle uses four plugs, or your factory specification lists another heat range or plug number.

FAQ

How do I know if my Hyundai Santa Fe needs new spark plugs?

Worn or fouled plugs can contribute to rough idle, difficult starting, hesitation, misfires, or reduced efficiency. Those symptoms are not unique to spark plugs, however. Ignition coils, fuel delivery problems, sensors, air leaks, and mechanical faults can produce similar symptoms, so diagnose persistent problems instead of replacing parts blindly.

What type of spark plugs are best for a Hyundai Santa Fe?

The best plug is the exact specification required by your engine, not simply the most expensive electrode material. Hyundai Santa Fe applications can use different plug numbers, heat ranges, gaps, thread dimensions, and electrode designs depending on year and engine. Match the factory specification or an approved cross-reference before buying.

Do Hyundai Santa Fe four-cylinder and V6 engines use the same spark plugs?

Not necessarily. Different engines can require completely different plug specifications. They also use different quantities: a four-cylinder normally needs four plugs, while a V6 needs six for a complete replacement. Never select a plug based only on the Santa Fe model name.

How often should I replace Hyundai Santa Fe spark plugs?

Replacement intervals vary by model year, engine, and the plug specification installed at the factory. Use the maintenance schedule for your exact Santa Fe rather than applying one mileage interval to every model. Inspect or diagnose the ignition system sooner if the engine develops relevant symptoms.

Can I replace Santa Fe spark plugs myself?

You can replace them yourself if you have the correct tools, specifications, and mechanical experience. Use the correct spark-plug socket and a torque wrench, work carefully around the ignition coils and connectors, and follow the factory tightening procedure. Access to the rear cylinder bank on some V6 engines can require additional disassembly.

Should I gap new spark plugs before installation?

Verify the supplied gap against your vehicle specification before installation, even when the plugs are advertised as pre-gapped. Fine-wire iridium electrodes can be damaged by rough adjustment, so use the proper checking method and avoid prying directly against the center electrode.
