Ignition Coil & Iridium Spark Plugs for Chevrolet Traverse (2009-2024) 3.6L V6

High-Voltage Ignition Coil & Iridium Spark Plugs for 2009-2024 Chevrolet Traverse (GM High Feature V6 / Lambda & C1XX)

Designed to restore optimal combustion efficiency, this comprehensive ignition coil and iridium spark plug kit replaces degrading factory components to eliminate misfires, rough idling, and hesitation under load.

The Stock Traverse Ignition System Shortcomings

The factory ignition coils on the 3.6L GM High Feature V6 engine are notoriously susceptible to thermal degradation due to their proximity to the cylinder heads and trapped under-hood ambient heat. Constant exposure to extreme operating temperatures causes the epoxy resin inside the OEM coil packs to fracture, leading to internal arcing, voltage leaks, and eventual failure. Furthermore, standard factory spark plugs experience accelerated electrode wear, gradually increasing the spark gap over time. This widened gap forces the ignition coils to work harder to bridge the electrical arc, creating a compounding cycle of strain that manifests as noticeable sluggishness, poor fuel economy, and dreaded P0300-series misfire codes, particularly when the engine is under towing or heavy passenger loads.

The Engineering Solution

This exact-fit replacement kit resolves these thermal and electrical vulnerabilities by utilizing upgraded ignition coils constructed with high-dielectric epoxy and reinforced polymer housings designed to withstand severe heat cycling without micro-cracking. Inside, precision-wound copper primary and secondary bobbins ensure a consistent, high-energy voltage output for a complete fuel burn. Paired with laser-welded iridium spark plugs, the system benefits from a much finer center electrode that requires significantly less voltage to generate a spark while providing superior resistance to spark erosion. The extremely high melting point of iridium ensures the factory-specified spark gap remains completely stable over tens of thousands of miles, maximizing fuel atomization, restoring crisp throttle response, and delivering consistent performance.
