Ignition Coil & Iridium Spark Plugs for Acura ZDX (2010-2013) 3.7L V6

High-Output Ignition Coils & Iridium Spark Plugs for 2010-2013 Acura ZDX (J37A5 / YB1)

Restores critical spark energy and combustion efficiency by replacing degraded factory ignition coils and fouled plugs on your 3.7-liter V6.

The Stock J37A5 Ignition Degradation

The J37A5 V6 is a robust engine, but as the YB1 chassis ages, the factory coil packs suffer from severe thermal stress. Positioned deep within the cylinder banks, the OEM coils endure continuous heat soak, which degrades the internal epoxy potting and primary windings. This thermal breakdown increases electrical resistance, causing weak spark output and eventual misfires under heavy load. Furthermore, standard spark plug electrodes wear down over time, widening the plug gap and forcing the weakened coils to overwork, resulting in sluggish throttle response, rough idle, and poor fuel economy.

The Engineering Solution

This direct-replacement kit integrates six high-dielectric epoxy ignition coils with six precision-gapped Iridium spark plugs. The upgraded coils feature advanced copper wire windings and high-temperature silicone boots designed to resist thermal breakdown and prevent voltage leaks, ensuring maximum energy transfer. By utilizing an Iridium center electrode, the spark plugs provide a significantly higher melting point than standard materials, maintaining a precise gap across intense combustion cycles. This optimized ignition sequence guarantees a complete, uniform fuel burn, translating to restored factory horsepower, stabilized idle, and maximized torque curve efficiency.
