Ignition Coil and Iridium Spark Plugs for GMC Canyon (2017-2020) 3.6L

Direct-Fit Ignition Coil and Iridium Plug Service Kit for 2017-2020 GMC Canyon

What it Does: Delivers complete secondary ignition renewal by replacing degraded factory coil packs and worn spark plugs to eliminate misfires, stabilize idle, and restore combustion efficiency in the 3.6L V6.

The Stock Canyon Ignition Breakdown

Under continuous thermal cycling and demanding trail or towing loads, factory coil packs on the GM LGZ 3.6L engine suffer from dielectric breakdown and internal winding degradation. In high-compression, direct-injected architectures, factory spark plug electrodes erode over time, widening the gap and forcing coils to draw excessive primary current. This results in intermittent P0300-P0306 misfire codes, hesitation under load, poor cold-start combustion, and reduced fuel efficiency.

The Engineering Solution

This direct-replacement kit provides high-dielectric coil-on-plug assemblies engineered with heavy-gauge pure copper internal windings and direct-fit blade terminals for maximum conductivity and thermal resistance. Paired with 6 fine-wire iridium spark plugs, the kit delivers a stable, high-voltage spark kernel capable of igniting lean direct-injection fuel charges under high cylinder pressure, preventing spark blowout and unburned hydrocarbon buildup.
