Ignition Coil & Spark Plug for Chevy SS (2015-2016) SSR (2005-2006) V8 (Round Style)

High-Output Ignition Coil & Spark Plug Kit for 2015-2016 Chevrolet SS & SSR

What it Does: This complete direct-replacement ignition package upgrades the factory GM ignition system to deliver a stronger, more consistent spark, preventing misfires and optimizing combustion efficiency.

The Stock LS-Series Ignition Weakness

Factory GM ignition coils on the LS2 and LS3 platforms suffer from severe thermal degradation. Positioned directly above the exhaust manifolds, these OEM coil packs endure constant heat cycling. This extreme temperature fluctuation breaks down the internal epoxy insulation, leading to micro-cracking and high-voltage leaks. As primary resistance increases, spark energy weakens, causing high-RPM misfires, sluggish throttle response, and incomplete fuel burn. Coupled with worn plug wires experiencing carbon tracking, the resulting voltage drop starves the chamber of the necessary spark intensity.

The Engineering Solution

To combat heat soak and voltage loss, this upgraded ignition set utilizes a high-grade epoxy internal construction paired with highly conductive internal copper wiring. Delivering a maximum output of 32,000V—up to 20% more energy than standard OE coils—this Round Style (UF414) coil ensures complete combustion. The primary resistance is dialed to 0.660 ohms for faster coil saturation and immediate discharge. The kit includes precision spark plugs and low-resistance ignition wires featuring thick silicone jackets to resist under-hood temperatures. Note: Always use dielectric silicone spray during assembly to prevent rubber boot tearing.
