Ignition Coil and Iridium Spark Plugs for Acura ILX (2013-2015) 2.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2013-2015 Acura ILX

What it Does: The ignition coil and iridium spark plug kit restores precise combustion timing, stabilizes engine idle, and resolves high-RPM misfires on the 2013-2015 Acura ILX 2.0L.

The Stock Acura ILX Secondary Ignition Breakdown

Factory coil-on-plug modules in the DE1 chassis endure extreme thermal cycling inside the tightly packed cylinder head of the R20A5 engine. Over time, internal epoxy insulation degrades, creating micro-fractures that induce primary and secondary winding shorts. Concurrently, factory spark plug gaps erode, elevating secondary voltage demand beyond the coil's threshold. This leads to dielectric boot breakdown, spark flashover, hesitation under load, and diagnostic trouble codes such as P0300 through P0304.

The Engineering Solution

This comprehensive service kit replaces worn ignition hardware with high-conductivity pencil coils and wear-resistant iridium spark plugs. The replacement ignition coils feature vacuum-poured polyurethane potting compound and high-grade copper windings to resist thermal shock and internal arcing. Coupled with fine-wire iridium-tipped center electrodes and platinum ground pads, this kit lowers required ignition breakdown voltage, minimizes flame kernel quenching, and guarantees crisp throttle response across the power band.
