Professional LS Ignition Coil Connector for Harness Builds & Repairs

This GM LS 3-Pin Ignition Coil Connector Kit is designed for OEM-style replacement and professional harness construction on LS-based engines and standalone EFI systems.

Built using the Delphi Aptiv Gen 3 connector family, this 3-pin coil plug provides secure terminal retention, sealed engine bay protection, and reliable ignition signal integrity in high-performance environments.

Available individually or in full sets of 4, this kit is ideal for both harness repair and complete LS ignition system builds.
