Product Details

NGK COP Ignition Coil Multi-Pack 49170 is part of NGK’s ignition coil line, developed with the brand’s long OE heritage and tested in an ISO 17025 accredited lab under demanding conditions.

This part cross-references Delphi GN10164 and DENSO Auto Parts 673-6000 for the same application.

Vehicle coverage includes long-tail search applications such as Ford F-150 ignition coil replacement, Ford Expedition COP ignition coil, and Lincoln Town Car coil-on-plug ignition service. The NGK 49170 listing also aligns with Ford E-Series van and Super Duty truck applications across multiple model years.

Common Problems This Part Addresses

Installation Notes and Tips

Verify the connector style, terminal count, and ignition system type before installation. Confirm the vehicle’s year, make, and model against the fitment list, especially on Ford F-150, Ford Explorer, and Mercury Grand Marquis applications. Inspect spark plugs and related ignition components during service, since worn plugs can shorten coil life and affect performance.
