Product Details

NGK 48674 is engineered as an OE-style ignition coil for vehicles that use a coil-on-plug ignition system. The design supports stable spark output and consistent ignition control, which is important for Subaru engines that rely on precise coil performance. This NGK COP Ignition Coil is a direct-fit service part for 2001-2009 Subaru Outback, 2006-2007 Subaru B9 Tribeca, 2008-2009 Subaru Legacy, and 2008-2009 Subaru Tribeca applications.

This part cross-references Delphi GN10435 for the same application.

What It Helps Address

• Engine misfire conditions related to weak ignition output
• Rough idle caused by inconsistent coil performance
• Hard starting from degraded ignition coil operation
• Loss of power under load from poor spark delivery
• Check engine light concerns tied to ignition coil faults

Installation Notes and Tips

Verify the connector style, terminal count, and ignition system type before installation. This NGK ignition coil uses a distributorless COP configuration, so it should be matched to the vehicle’s original coil-on-plug setup. Confirm fitment by year, make, and model before replacing the existing coil.

For Subaru Legacy and Subaru Outback ignition coil replacement, as well as Subaru Tribeca and Subaru B9 Tribeca service, inspect the spark plug condition and related ignition components during diagnosis to help isolate the root cause of the fault.

Quality Assurance

NGK manufactures ignition coils to meet or exceed OE standards and validates designs through testing in an ISO 17025 accredited laboratory. The brand’s long OE legacy and broad vehicle coverage support confidence in service replacement for supported Subaru applications.
