A-Premium Ignition Coil and Iridium Spark Plug Kit — Set of 4 for Hyundai/Kia 1.8L–2.0L, Direct Fit, Long-Life Iridium

Complete set of four A-Premium ignition coils and matching iridium spark plugs engineered as direct replacements for select Hyundai Elantra, Kia Forte, Soul and related 1.8L–2.0L engines.

This kit combines four bolt-on ignition coils with four iridium-tipped spark plugs to restore firing consistency, improve starting response and maintain fuel burn stability across compatible Hyundai and Kia 4-cylinder models. Each coil uses a dual-blade terminal and mounts to the valve cover for straightforward installation; the iridium center electrode increases service life and helps sustain a steady idle.

Which vehicles will this A-Premium kit fit?

The set is built to replace OEM units on a range of Hyundai and Kia models with 1.8L and 2.0L 4-cylinder engines. It covers multiple model years and trims; always verify part numbers and engine codes before purchase.

• Hyundai Elantra: 2012 (1.8L), 2013–2016 (1.8L), 2014 (2.0L), 2015 (2.0L to 12/2015, 2-terminal), Elantra Coupe/GT: select 2013–2014, Elantra GT/Tucson: 2014–2020 with 2.0L
• Kia Forte/Forte Koup/Forte5: 2014–2018 coverage for 1.8L and 2.0L variants (note: some years use 2-terminal configuration)
• Kia Soul (2.0L): 2012–2019; Kia Rondo 2014 (2.0L)
• Cross-check reference numbers UF-651 / UF651 / 273002E000 / C1804 to confirm compatibility.

What are the key specifications and installation details?

These coils and plugs are designed to match OEM fit and electrical characteristics so they behave like factory replacements. Basic electrical resistances, mounting type and spark plug dimensions are provided to help technicians and DIY mechanics install correctly.

• Coil terminals: 2-blade; mount type: bolt-on to valve cover
• Primary resistance: 0.77 ohm; secondary resistance: 7.7 KΩ
• Spark plug: iridium center electrode with nickel ground; thread diameter 12 mm; gap 0.7–0.8 in
• Recommended installation torque for spark plugs: 15–20 N·m (follow vehicle service manual)

Why choose iridium spark plugs with new coils?

Iridium-tipped plugs use a harder, higher-melting-point alloy at the center electrode, which helps resist erosion and sustain a narrow gap for longer. Pairing fresh plugs with new coils reduces misfires and uneven idling that can occur when aging ignition components work against each other.

• Iridium electrode extends plug life—often several times longer than standard plugs
• Narrower gap supports stable spark and consistent combustion
• New coils restore voltage delivery for clean ignition and crisper starts

What warranty and support come with the set?

The kit includes customer support and a limited warranty to protect against manufacturing defects. A-Premium offers a one-year unlimited-mileage warranty and assistance if the parts fail under normal use.

• 1-year unlimited-mileage warranty from A-Premium
• Designed as direct replacement — plug-and-play for compatible engines
• Reference numbers included for parts verification before ordering

Who is this for? DIY mechanics and professional technicians who need a matched set of ignition coils and long-life spark plugs for mid-2010s Hyundai and Kia 1.8L–2.0L 4-cylinder engines. It suits owners seeking reliable replacements that mirror OE mounting and electrical specs, plus drivers wanting the extended service life and steady idle delivered by iridium plugs. Always confirm vehicle fitment and service torque values against your model's workshop manual before installation.
