Delphi Ignition Coil GN10172 - Direct-Fit OE-Style, Precision Winding & Long Life

Delphi GN10172 Ignition Coil is a direct-fit, OE-style ignition coil that delivers consistent spark energy to help ensure reliable starting and steady engine performance.

This Delphi ignition coil is built to function as part of your vehicle's engine management system, supplying voltage to spark plugs and supporting responsive combustion under everyday driving conditions. Designed and tested using Delphi’s long history of OE engineering, the GN10172 meets demanding manufacturing standards and comes with the necessary accessories for installation. It focuses on precise voltage delivery, long service life, and compatibility with compatible vehicle applications to help maintain smooth operation and reduce ignition-related interruptions.

How does this ignition coil improve vehicle starting and idle?

The GN10172 provides consistent high-voltage output to spark plugs so ignition timing remains reliable at startup and during idle. That steady spark helps the engine fire predictably, reducing missed ignitions and rough idling when the coil is functioning properly.

• Consistent spark energy for fewer misfires
• Precision-wound coil for stable voltage delivery
• OE-style fit to preserve factory ignition timing
• Includes installation accessories for a full replacement job
