Ignition Coil & Iridium Spark Plugs for Acura RSX (2002-2006) 2.0L

Direct-Replacement Ignition Coils & Iridium Spark Plugs for 2002-2006 Acura RSX

Restores lost power and eliminates misfires: This complete ignition service kit replaces worn factory coils and fouled plugs to ensure consistent spark delivery and optimal fuel combustion under all driving conditions.

The Stock RSX Ignition Degradation

The original equipment ignition coils on the DC5 chassis endure extreme thermal cycling, especially in the high-revving K20 engine bays. Over time, the internal epoxy potting compound degrades and cracks. This thermal breakdown compromises the secondary windings, causing voltage leaks and intermittent misfires under load. Concurrently, aging factory spark plugs suffer from electrode wear and carbon fouling, increasing the required firing voltage and further straining the coil packs. This compounding failure leads to sluggish throttle response, rough idling, decreased fuel economy, and dreaded cylinder misfire trouble codes.

The Engineering Solution

This ignition service kit resolves inherent K-series spark delivery issues by upgrading the system's core components. The replacement ignition coils feature high-dielectric epoxy and reinforced thermal plastic housings to actively resist heat soak and prevent voltage bleed. Upgraded internal copper windings ensure efficient energy transfer, maximizing voltage output directly to the plugs. Paired with premium iridium spark plugs, the ultra-fine center electrodes focus spark energy, significantly reducing the voltage threshold required to bridge the gap. Iridium's superior melting point guarantees long-term durability and resistance to spark erosion. Combined, this kit restores precise ignition timing, stabilizes idle vacuum, and ensures a complete burn of the air-fuel mixture up to the factory redline.
