Product Details

Delphi GN10314 is an ignition coil engineered for vehicles that use a coil-on-plug setup. This style mounts directly at the spark plug location and helps maintain consistent ignition performance across the engine’s operating range. It is a practical replacement for drivers searching for a Toyota Corolla ignition coil, Toyota Matrix ignition coil, or Pontiac Vibe ignition coil with confirmed fitment across model years from 2000 through 2008.

Compatible With 2003-2008 Pontiac Vibe, N/A; 2000-2008 Toyota Corolla, N/A; 2003-2008 Toyota Matrix, N/A; 2000-2005 Toyota Celica, N/A; 2000-2005 Toyota MR2 Spyder, N/A; and 2000-2002 Chevrolet Prizm, N/A. The Delphi GN10314 part number is also a useful reference when comparing ignition coil replacements for these applications.

What It Helps Address

• Engine misfire caused by weak or inconsistent spark output
• Rough idle related to ignition coil wear
• Hard starting from degraded coil performance
• Loss of acceleration response under load
• Check engine light concerns tied to ignition system faults

Installation Notes and Tips

Verify the terminal style, terminal count, and coil-on-plug layout before installation. Inspect the spark plug, connector, and wiring harness for heat damage or corrosion before fitting the new coil. For best results, confirm vehicle application by year, make, and model before ordering GN10314.

Quality Assurance

Delphi builds this ignition coil using OE heritage and knowledge developed through long-term original equipment experience. That background supports consistent fit and function for the listed Toyota Corolla, Toyota Matrix, and related applications.
