5 Best Spark Plugs For 2017 Hyundai Elantra

If you drive a 2017 Hyundai Elantra, replacing worn spark plugs is one of the smartest maintenance moves you can make. Better spark plugs help your engine run smoother, restore lost power and can improve fuel economy — which means fewer trips to the pump and a more reliable daily drive.

This guide helps you pick parts that fit the Elantra’s 2.0L engine, explains what to look for, and points you to kits that include coils and plugs when a full replacement makes sense.

Top Picks

How We Picked

You want spark plugs that match your Elantra’s 2.0L engine and the factory thread/gap specs, so compatibility is the first filter. Next, you should consider electrode material: iridium or platinum plugs offer longer life and more consistent ignition than basic copper plugs.

If you’re replacing misfiring cylinders or dealing with coil failures, kits that include ignition coils and spark plugs can save time and ensure matched performance. We also weighed real-world customer ratings and reviews, value (price vs.

expected lifespan), and ease of installation — especially if you plan to do the job yourself. Finally, we checked part numbers commonly listed for the Elantra 2.0L (examples include 27300-2E601 and reference numbers such as 93175) so you can quickly cross-check fitment for your VIN or engine code.

RANSOTO UF816 Coil Pack & Iridium Plugs (Set of 4)

If you’re swapping spark plugs and coil packs on a 2017 Hyundai Elantra 2.0L, this RANSOTO kit is built to be a straightforward, vehicle-specific option. It pairs coil-on-plug units with iridium plugs, so you get a direct-replacement fit that aims to match OE specs.

Because the parts are designed for the same fit and function as the originals, you shouldn’t need to modify anything — which makes installation a lot less stressful if you like doing basic maintenance yourself. For daily driving, you’ll notice the benefit in smoother starts, fewer misfires, and steadier idling when the ignition components are healthy. For special situations like long road trips or towing-like loads where the engine runs for extended periods, the higher electrical resistance and corrosion-resistant materials help the components tolerate heat and wear a bit better than cheaper alternatives. If you’re comfortable with basic DIY work or just want a direct replacement that reduces the chances of fitment headaches at the shop, this kit is a practical choice.

It’s not making wild performance promises — it’s intended to restore reliable ignition and keep things running cleanly so you can get on with your day.

TEMSONE UF816 Coil Packs & Spark Plugs (Set of 4)

If you’re dealing with rough idles, occasional misfires or a check-engine light that points to ignition trouble, this TEMSONE UF816 kit is the kind of plug-and-play swap that makes life easier. It ships as a set of four coil packs with matching spark plugs, listed for a wide range of 2.0L Hyundai/Kia engines including 2017 Elantra 2.0L — so it’s a good match if your car is the same spec.

For everyday driving you’ll likely notice smoother idling and steadier starts after replacing worn parts; for longer trips or cold mornings it helps avoid flaky starts and intermittent misses. The coils are filled with high-insulation epoxy and use quality copper windings, which is meant to keep moisture out and resist thermal breakdown. If your symptoms are ignition-related and the fitment checks out, this kit is a practical, wallet-friendly replacement to try before more invasive troubleshooting.

Buyers frequently call this kit a good value that ‘gets the job done’ — several owners reported replacing a single bad cylinder and seeing noticeably better running afterward. You should be aware some buyers flagged fitment or packaging concerns, so double-check your OEM part number before ordering.

Overall Sentiment: Positive

Durability

The coils are molded with high-insulation epoxy and use copper wire windings to limit moisture intrusion and thermal breakdown — built to handle repeated heat cycles common in daily driving and longer trips.

Fixes and Symptoms

Good at addressing ignition-related symptoms like misfires, rough idle, poor starts and related check-engine codes. It won’t cure problems caused by bad wiring, fuel delivery, sensors or unrelated engine issues, so verify the ignition circuit before assuming plugs/coils are the only fault.

FAQ

How Do I Choose The Best Spark Plugs For My 2017 Hyundai Elantra?

You should pick plugs that match your engine’s specifications and OEM part numbers (common cross-references you may see include 27300-2E601, 93175, and LKR7DIX-11S). Prioritize iridium or platinum electrodes for longer life and more consistent spark compared with copper, and confirm thread size and gap are correct for the 2017 Elantra 2.0L.

Check compatibility with coil-on-plug setups and look for parts labeled as vehicle-specific fit; matching the OEM heat range and gap is more important than brand alone. If you’re unsure, compare the new plug’s specifications to the ones removed or consult your owner’s manual to ensure proper fit and performance.

Can I Replace Just The Spark Plugs Or Should I Replace Ignition Coils Too?

You can replace just the spark plugs if the ignition coils test and look fine, but many owners choose a combined coil-and-plug kit when they have persistent misfires or aged components. If you see one or more misfire codes, rough idle, or poor acceleration after installing new plugs, the coil(s) may be failing and should be replaced.

Consider replacing coils when they’re cracked, have damaged boots, or electrical tests show out-of-spec resistance; otherwise you can save money by changing only the plugs. A practical rule is to inspect coils during plug service and replace any coil that shows wear—this avoids repeated labor and helps restore consistent engine performance.

What Are The Signs Of Worn Spark Plugs And How Do I Install New Ones Safely?

Signs of worn plugs include rough idle, intermittent misfire, reduced fuel economy, sluggish acceleration, and a persistent check engine light. For safe installation, work on a cool engine, disconnect the ignition connector before removing coils, gently remove coils and plugs, check and set the plug gap to the manufacturer’s spec, and use a torque wrench to tighten to the factory torque (consult your owner’s manual for the exact value).

Avoid putting dielectric grease on the plug threads—use a tiny amount inside the coil boot if needed—and don’t apply anti-seize unless the manufacturer recommends it, because some modern plugs are pre-coated. Finally, replace all four plugs at once for even performance and inspect coil boots and wiring while you have access.

What Buyers Prefer

When choosing between these options you’ll mainly look for compatibility with your Elantra, whether the kit includes coil packs or just plugs, and the plug material—iridium or iridium/platinum—for longevity and stronger spark. You’ll also weigh ease of installation, OEM fit and reliability, and overall value, picking the coil+plug kits if you want a more complete replacement or the A-Premium plugs if you want a durable, budget-friendly standalone option.

Wrapping Up

To get your 2017 Hyundai Elantra running its best, prioritize correct fitment and choose iridium or platinum plugs for longer service life and steadier performance. If you have a misfire or repeated coil issues, go with a complete coil+plug kit so you replace all likely failure points at once.

The X4XZ UF816 kit is our top pick for an all-around balance of quality and price, while the A-Premium 2017–2020 pack is a strong low-cost choice if you only need plugs. Always confirm the part number and compatibility with your engine before buying so you get the part that fits and performs as expected.
