Ignition Coil & Iridium Spark Plugs for Chevrolet Camaro (2010-2015) 3.6L V6

High-Energy Ignition Coil & Iridium Spark Plugs for 2010-2015 Chevrolet Camaro Replaces degrading OEM ignition components to restore optimal combustion, eliminate misfires, and stabilize idle in the 3.6L High Feature V6. The Stock Camaro Ignition Degradation Over time, the factory ignition system on the 3.6L High Feature V6 (both the LLT and LFX variants) experiences severe thermal stress. The constant heat cycling within the tight engine bay degrades the epoxy resin inside the OEM ignition coils, leading to internal micro-fractures. These fractures allow voltage to arc directly to the engine block rather than traveling down to the spark plug, resulting in intermittent misfires, erratic idling, and a noticeable loss of low-end torque. Furthermore, standard factory spark plugs suffer from accelerated electrode wear under sustained loads, widening the spark gap and forcing the coils to overwork, compounding the failure cycle and triggering P0300-series CEL codes. The Engineering Solution This complete ignition overhaul directly addresses the thermal and electrical shortcomings of the OEM setup. The included ignition coils are constructed with high-temperature epoxy and upgraded primary and secondary copper windings, reducing electrical resistance and preventing the thermal breakdown that plagues standard units. This ensures a consistent, high-voltage spark delivery even under extreme engine bay temperatures. Paired with heavy-duty iridium spark plugs, the system maximizes burn efficiency. The ultra-fine iridium center electrode requires less voltage to jump the gap, reducing the electrical load on the coils while providing exceptional resistance to oxidation and spark erosion. This translates to sharper throttle response, restored fuel economy, and reliable high-RPM performance without misfires.
