Ignition Coil & Iridium Spark Plugs & Wire for Cadillac Escalade ESV (2017-2020) 6.2L V8

High-Output Ignition Coil & Iridium Spark Plug Kit for 2017-2020 Cadillac Escalade

What it does: Replaces degraded factory ignition components with higher-voltage coils, 8mm shielded wires, and iridium plugs to eliminate misfires and restore optimal combustion efficiency.

The Stock Escalade Ignition Shortcomings

The factory ignition system on the 6.2L L86 V8 is highly susceptible to thermal degradation over high-mileage heat cycles. Prolonged exposure to engine bay temperatures compromises the dielectric integrity of the OE coil epoxy and wire insulation. This insulation breakdown leads to voltage leaks, resulting in inconsistent spark delivery, cylinder misfires, hesitation under heavy load, and reduced fuel economy. Furthermore, as factory spark plugs wear, the spark gap increases. This forces the standard ignition coils to work significantly harder to bridge the gap, which accelerates their eventual failure and often triggers check engine light (CEL) circuit malfunction codes.

The Engineering Solution

This comprehensive ignition overhaul addresses OE failure points by utilizing upgraded materials for superior thermal stability and electrical conductivity. The enhanced coil packs deliver 20% more energy than standard units, stepping up a 12-volt primary charge to a robust 26,000-volt maximum secondary output. Built with premium copper internals and high-temperature resistant silicone boots, these epoxy-filled coils resist heat soak, vibration, and corrosion. Paired with 8mm high-density spark plug wires featuring protective heat shields and premium Iridium spark plugs (41-114), this system ensures a powerful, stable spark. Iridium’s extremely high melting point guarantees a consistent spark gap over time, maximizing combustion efficiency, mitigating pre-ignition risks, and restoring peak engine power and smooth idling characteristics.
