The result is a replacement ignition coil intended to match OE fit and electrical requirements while supporting reliable engine operation in everyday driving.

This part cross-references DENSO Auto Parts 673-1305 and Standard Ignition UF-314 for the same application.

Common Issues This Coil Can Address

• Engine misfire under load or at idle
• Rough running after startup
• Hard starting caused by weak ignition output
• Check engine light related to ignition coil performance
• Loss of power from inconsistent spark delivery

Installation Notes and Tips

Confirm the connector style, terminal layout, and engine application before installation. Inspect the spark plug and coil boot area for oil contamination, corrosion, or carbon tracking, since these conditions can affect coil performance. For best results, replace any worn spark plugs at the same time and clear diagnostic trouble codes after installation.
