This part cross-references Standard Ignition UF-350 for the same application. It also cross-references Delphi GN10219 for the same application.

Vehicle Fitment

• Fits 2002-2006 Nissan Altima, N/A
• Fits 2002-2006 Nissan Sentra, N/A
• Fits 2005-2006 Nissan X-Trail, N/A

Common Issues This Coil Can Address

• Engine misfire caused by weak ignition output
• Rough idle related to coil degradation
• Hard starting from inconsistent spark delivery
• Loss of power under load due to ignition breakdown
• Check engine light conditions tied to ignition coil failure

Installation Notes

Verify connector style, terminal count, and engine application before installation. This coil uses a blade-style terminal layout and a female connector, so matching the original electrical interface is important for proper fitment. Inspect the spark plug and surrounding ignition components during service to help prevent repeat failures.
