Ignition Coil & Iridium Spark Plugs for Nissan Pathfinder (2001-2012) 3.5L 4.0L V6

Direct-Fit Ignition Coil & Iridium Spark Plugs for 2001-2012 Nissan Pathfinder

Restores lost power and resolves misfire codes: This complete ignition service kit replaces degrading factory coils and fouled plugs to ensure consistent spark delivery and optimal combustion in high-mileage VQ engines.

The Stock Pathfinder Ignition Degradation

The factory ignition coils on the VQ35DE and VQ40DE engines are notorious for thermal degradation over time. Positioned directly above the cylinder head, these coils endure extreme heat cycling that breaks down the internal epoxy potting and compromises the secondary winding insulation. This breakdown leads to internal voltage leaks, weak spark output, and eventually consistent P0300 or specific cylinder misfire codes. Additionally, the OEM spark plug electrodes wear down over tens of thousands of miles, increasing the required firing voltage. This places even more strain on the already compromised factory coil packs, resulting in sluggish throttle response, reduced fuel economy, and rough idling under load.

The Engineering Solution

This comprehensive ignition kit utilizes upgraded primary and secondary copper windings housed in a high-dielectric epoxy resin, significantly improving thermal resistance and preventing the voltage leaks common in OEM units. The durable thermoplastic housings withstand extreme engine bay temperatures without cracking. Paired with high-performance iridium spark plugs, this kit ensures a concentrated, stable spark at a lower required firing voltage. The iridium center electrode boasts exceptional hardness and a high melting point, drastically reducing wear rates compared to standard platinum or copper plugs. By delivering a more complete combustion cycle, this engineered pairing effectively eliminates misfires, stabilizes idle quality, and restores factory horsepower and torque curves across the entire RPM band.
