Detailed Description

Delphi GN10309 is an ignition coil designed for vehicles that use a coil-on-plug ignition setup, where each coil mounts directly to the spark plug location. This design supports consistent spark output and straightforward replacement on the listed applications. Delphi applies its OE heritage and manufacturing experience to aftermarket ignition parts, making this coil a practical choice for service on vehicles such as the 2004-2009 Cadillac CTS, 2005-2009 Cadillac STS, 2009 Chevrolet Traverse, and 2009 GMC Acadia. This part cross-references Standard Ignition UF-375 for the same application.
