Detailed Description

Delphi GN10438 is an ignition coil engineered for select 1999-2001 Mazda Protege applications. Delphi draws on long-standing OE heritage and supplier experience with major automakers, and that engineering background is reflected in the fit, connector style, and ignition performance of this replacement coil. This part cross-references Standard Ignition UF-276 and Beck/Arnley 178-8255 for the same application.

Use GN10438 when you need a replacement ignition coil for a Mazda Protege that uses a coil-on-plug setup with boot and spring hardware at the spark plug end. The part number GN10438 is also a useful reference when verifying the correct ignition coil for 1999, 2000, and 2001 Mazda Protege vehicles.

What It Helps Fix

• Engine misfire caused by weak or inconsistent coil output
• Hard starting related to ignition spark loss
• Rough idle from degraded coil performance
• Acceleration hesitation tied to intermittent ignition delivery
• Check engine light conditions associated with ignition coil faults

Installation Notes and Tips

Confirm the vehicle uses the listed coil-on-plug configuration before installation. Inspect the boot and spring condition during service, and verify the 3-terminal blade connector seats fully before starting the engine. For best results, compare the original coil shape and connector layout to Delphi GN10438 before removal.
