A-Premium Ignition Coil and Iridium Spark Plug Kit — Set of 4 for 2.4L Honda & Acura, Direct-Fit Long-Life

High-quality set of four ignition coils and four iridium spark plugs engineered to replace worn units on 2.4L Honda and Acura engines for reliable starts and smoother running.

This A-Premium kit pairs direct-fit coil packs with long-life iridium spark plugs so you can restore consistent ignition timing, improve throttle response, and reduce misfires without modifying the engine. Each coil is built to OEM-style specifications and the iridium center electrode offers extended service life compared with standard plugs. The parts are compatible with selected Acura ILX and multiple Honda models that use the 2.4L L4 engine (see fitment list below).

Which vehicles will this ignition coil and spark plug kit fit?

The kit fits many 2.4L L4 applications from Honda and Acura. Confirm engine code and year before purchase to ensure direct compatibility.

• Acura ILX 2013–2015 L4 2.4L
• Honda Accord 2008–2012 L4 2.4L
• Honda Civic 2012–2015 L4 2.4L
• Honda CR-V 2010–2014 L4 2.4L
• Honda Crosstour 2012–2015 L4 2.4L

How do the A-Premium coils and iridium plugs improve engine performance?

The coil packs provide the necessary high-voltage pulse while the iridium plugs create a reliable spark with a fine, durable electrode. Together they help maintain stable idling, reduce the chance of misfires, and deliver more consistent combustion across cylinders.

• Coil specs: 3 terminals, blade-type, bolt-on mount to valve cover
• Primary resistance: 0.86–1.05 Ω; secondary resistance: 5.5–6.7 kΩ
• Iridium + nickel center electrode for extended life and stable spark
• Recommended spark plug gap: 0.7–0.8 in; thread diameter: 12 mm

What should I know about installation and torque settings?

Installation follows the original mounting points on the valve cover and uses bolt-on hardware for a straightforward swap. Always replace coils and plugs with the engine cool and follow the correct torque values to avoid damage.

• Mount type: bolt-on to valve cover — direct OEM fit
• Terminal type: blade with 3 terminal connections
• Installation torque for spark plugs: 15–20 N·m (follow vehicle manual for sequence)
• Reference number: UF-602 (UF602) for parts lookup

How long will the iridium spark plugs and coils last?

Iridium-plated center electrodes are more wear-resistant than standard nickel plugs, typically offering a longer service interval under normal driving conditions. Coil life depends on heat cycles and electrical stress, but replacing both coils and plugs together reduces failure risks and balances cylinder performance.

• Iridium plugs often last multiple service intervals versus conventional plugs
• Coils meet specified resistance ranges to help ensure predictable operation
• A-Premium backs the kit with a one-year unlimited-mileage guarantee

Who is this for: This A-Premium four-coil and four-plug kit is for owners and technicians who want a direct-replacement ignition solution for 2.4L Honda and Acura engines. It suits DIYers doing scheduled spark maintenance and shop professionals replacing misfiring or aged ignition components. Confirm model year and engine size before ordering to ensure a perfect fit.
