Product Details

NGK ignition coils are engineered to meet or exceed OE standards, with manufacturing and testing processes built around durability and operational consistency. This NGK COP ignition coil is developed for late-model domestic and import coverage, including Subaru Legacy and Subaru Outback vehicles in the 2010-2012 range. The pencil-type coil design supports direct ignition control at the plug, helping maintain stable spark output under normal engine operating conditions. This part cross-references Standard Ignition UF-668 for the same application.

Common Issues This Part Can Address

• Engine misfire caused by a weak or failing ignition coil
• Rough idle related to inconsistent spark output
• Hard starting from degraded coil performance
• Check engine light concerns tied to ignition coil faults
• Loss of acceleration response from intermittent ignition delivery

Installation Notes and Tips

Verify connector style, terminal layout, and engine application before installation. This coil uses a female connector, male terminals, and a blade-style terminal design, so matching the original electrical interface is important. Confirm the vehicle is a 2010-2012 Subaru Legacy or 2010-2012 Subaru Outback before ordering. For best results, inspect spark plugs and related ignition components during service, since worn plugs can place added load on the coil.
