Ignition Coil + Spark Plugs for GMC Savana (2017-2018) 6.0L

High-Output Ignition Coil and NGK Platinum Spark Plug Kit for 2017-2018 GMC Savana (GMT610)

What it Does: The complete ignition kit replaces worn factory ignition components on the 2017-2018 Savana to eliminate under-load misfires, stabilize idle combustion, and restore consistent spark delivery.

The Stock GMC Savana Secondary Ignition Breakdown

In high-mileage commercial service, the factory coil packs on the GM GMT610 platform face extreme under-hood thermal saturation. Repeated thermal cycles degrade the internal epoxy insulation and primary/secondary copper windings, leading to internal short circuits, dielectric breakdown, and secondary voltage leakages. Coupled with factory spark plugs eroded past service limits, the increased gap resistance strains the coil drivers, producing severe hesitation, erratic idle quality, and catalyst-damaging misfire codes under heavy towing payloads.

The Engineering Solution

This comprehensive service kit pairs high-dielectric replacement coil packs with genuine fine-wire NGK Platinum spark plugs to establish factory-grade secondary spark energy. The ignition coils are constructed with high-grade magnetic silicon steel cores and temperature-resistant thermoplastic housings to resist electrical arching and thermal potting fatigue. Paired with platinum-tipped spark plug center electrodes that minimize electrical erosion and preserve precise gap tolerances, this setup ensures consistent flame kernel development across all cylinders in high-demand L96 engine cycles.

Frequently Asked Questions & Fitment Warnings

Does this fit the GMT610 Savana?

Yes, this is a direct fit for the 2017-2018 GMC Savana equipped with the L96 6.0L V8 engine. It is not compatible with 4.3L V6, 6.6L Duramax Diesel, or 2.8L Duramax Turbo-Diesel configurations.

Are high-voltage spark plug wires included with this kit?

No, spark plug wires are not included; this set includes only the 8 replacement ignition coils and 8 NGK platinum spark plugs for your coil-on-plug bracket setup.

The GMC Heavy-Duty Commercial Standard

Fleet platforms require sustained electrical reliability under brutal commercial duty cycles; fresh secondary ignition components ensure optimal torque recovery, steady fuel trim regulation, and unimpeded towing capacity under load.
