Ignition Coil and Iridium Spark Plugs for Honda Accord Crosstour (2010-2011) 3.5L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2010-2011 Honda Accord Crosstour

What it Does: The Ignition Coil and Iridium Spark Plug Kit restores complete secondary ignition combustion efficiency across all cylinders on the 2010-2011 Accord Crosstour, eliminating high-load misfires and rough idling.

The Stock Honda Accord Crosstour Ignition Breakdown

Factory ignition coils mounted deep in the cylinder heads of the TF1/TF2 chassis endure severe continuous thermal cycling. Over time, internal epoxy insulation breaks down and secondary winding resistance degrades within the factory coil packs. This causes dielectric breakdown, spark blowout under heavy throttle, and intermittent P0300-P0306 misfire codes on the J35Z2 engine. Worn factory plugs simultaneously increase required firing voltages, accelerating coil fatigue and degrading fuel economy.

The Engineering Solution

This complete ignition service kit replaces deteriorated components with high-output pencil coils and high-durability iridium spark plugs. Designed to meet or exceed OEM specifications such as 30520R70A01 and UF603, the replacement coils utilize high-grade dielectric epoxy potting and heavy-duty silicone boots to prevent micro-arcing and moisture intrusion. Paired with fine-wire iridium center electrodes, the system lowers required breakdown voltage, maintains consistent flame-front kernel propagation across all six combustion chambers, and smooths engine operation during VCM cylinder transitions.
