Ignition Coil & Iridium Spark Plugs for Honda Crosstour (2008-2012) 3.5L V6

Direct-Replacement Ignition Coil & Iridium Spark Plugs for 2008-2012 Honda Crosstour (J35Z2 / TF1/TF2)

Restores spark output and combustion efficiency: This comprehensive kit replaces aging factory coils and plugs to eliminate misfires, stabilize idle, and maximize fuel economy for the 3.5L V6.

The Stock Crosstour Ignition Weakness

The factory Honda J35 V6 ignition coils, specifically the epoxy-filled units, are prone to thermal degradation over high-mileage cycles. Nestled tightly against the cylinder heads, these coils endure intense under-hood temperatures. Over time, heat soak breaks down the internal primary and secondary copper windings, leading to voltage leaks, intermittent misfires, and a noticeable drop in throttle response. Coupled with worn factory spark plugs experiencing widened electrode gaps, the engine struggles with incomplete combustion, increasing unburned hydrocarbon emissions and frequently triggering P0300-series CEL codes.

The Engineering Solution

This kit mitigates voltage loss by utilizing high-dielectric epoxy resin inside the replacement ignition coils, insulating the windings against extreme heat soak and engine vibration. The upgraded internal magnetic steel cores provide faster charge times and a consistently high-energy spark output. Paired with performance iridium spark plugs, which feature an ultra-fine center electrode, the system requires less voltage to bridge the gap. Iridium's superior high melting point drastically reduces gap erosion compared to standard copper or platinum plugs, ensuring a precise, focused spark for optimal flame kernel growth. The hardware features OEM-correct blade connectors for a plug-and-play installation without wire splicing.
