Detailed Description

Delphi GN10454 is an ignition coil designed for vehicles that use a coil-on-plug ignition setup. This style mounts directly at the spark plug location, helping restore proper ignition output when the original coil begins to fail. It is a direct replacement for select applications including the 2007-2012 Chevrolet Colorado, 2007-2012 GMC Canyon, and 2007-2010 Hummer H3, along with other listed GM-platform vehicles. This part cross-references Standard Ignition UF-497 and DENSO Auto Parts 673-7003 for the same application.

Common Problems This Part Can Address

• Engine misfire caused by a weak or failing ignition coil
• Rough idle related to inconsistent spark delivery
• Hard starting from degraded coil performance
• Check engine light triggered by ignition system faults
• Loss of power under load from intermittent spark output

Installation Notes and Tips

Verify connector style, terminal count, and engine application before installation. The GN10454 uses a 3-terminal male blade connection and is listed for coil-on-plug ignition systems. On 2008 Isuzu i-370 applications, fitment notes specify use with boot and spring. Inspect the spark plug, boot, and related ignition components during service to help prevent repeat failures.

Quality Assurance

Delphi builds aftermarket parts using OE heritage and knowledge developed through long-term supplier experience with major automakers. The GN10454 is engineered to meet the needs of the listed applications and to support reliable ignition system service on compatible Chevrolet Colorado, GMC Canyon, and related vehicles.
