Ignition Coil & Iridium Spark Plugs for Honda Ridgeline (2009-2014) 3.5L V6

High-Output Ignition Coil & Iridium Spark Plugs for 2009-2014 Honda Ridgeline (J35Z5 / YK1)

Replaces failing factory ignition components to restore optimal spark delivery, eliminate misfires, and improve combustion efficiency in the 3.5L V6.

The Stock Ridgeline Ignition Weakness

The OEM ignition coils on the J35 V6 engines are notorious for degrading under prolonged thermal stress, especially when subjected to heavy loads, towing, or high-mileage heat cycling. Over time, the internal epoxy potting breaks down, increasing electrical resistance and leading to weak spark output. This failure manifests mechanically as intermittent misfires under load, rough idling, hesitation during acceleration, and ultimately triggers P0300-series diagnostic trouble codes. When paired with aging factory spark plugs that suffer from widened gaps due to electrode erosion, the stock ignition system struggles to maintain a complete fuel burn, significantly sacrificing both engine responsiveness and overall fuel economy.

The Engineering Solution

This comprehensive 6-pack of upgraded ignition coils and iridium spark plugs is engineered to deliver a concentrated, high-voltage spark throughout the J35's entire RPM range. The coils feature high-conductive copper wire primary and secondary windings encased in superior dielectric epoxy to resist thermal breakdown and prevent high-voltage leaks under load. Paired with precision iridium-tipped spark plugs—which boast an ultra-fine center electrode requiring less voltage to fire while offering exceptional resistance to heat and wear—this kit guarantees consistent, powerful spark energy. The result is optimized flame propagation within the combustion chamber, translating directly to restored horsepower, stabilized idle parameters, improved throttle response, and robust long-term reliability.
