LSX ignition Coil Kit

The Chevrolet Performance LSX Ignition Coil Kit (part number 19367577) is a complete ignition coil solution engineered for GM LS-series and GM GenV LT-series engines. This epoxy-filled coil pack kit delivers factory-matched ignition timing and spark consistency across all cylinders, making it essential for street engines, crate motor builds, and performance restorations that demand reliable starting and consistent combustion chamber ignition.

The kit features female socket connectors and includes coil wire and wire harness components, eliminating the need for sourcing separate ignition harnesses during installation. Epoxy potting protects the internal coil windings from vibration, moisture, and thermal cycling—common challenges in high-output LS and LT engine installations where underhood temperatures and engine vibration are elevated. The complete kit approach simplifies wiring integration and reduces troubleshooting time during engine assembly or retrofit work.

This coil kit is designed for builders and enthusiasts restoring or upgrading LS-based platforms—including C5 and C6 Corvettes, Camaros, Trucks, and crate motor applications. Whether you're installing a replacement ignition system on an original LS engine or outfitting a fresh crate motor build, this Chevrolet Performance kit ensures proper voltage delivery and ignition timing without the guesswork of aftermarket-only solutions. Compatibility with both LS-series (5.3L, 5.7L, 6.0L) and GenV LT-series (5.3L, 6.2L) engines makes it a versatile choice across GM's modern performance lineup.
