Spark Plug
- Description:
This genuine Ford Motorcraft double platinum spark plug delivers the ignition spark that fires the air-fuel mixture in each cylinder, a critical ignition component on the three-valve modular engines it serves. It is the revised single-piece design that addresses the broken-plug failure mode of the earlier two-piece plug and is the correct application for 2008-2019 F-150, F-250 and F-350 Super Duty, Expedition, Explorer, Sport Trac, Mustang and Navigator models with 4.6L 3V, 5.4L 3V and 6.8L V10 engines, cross-referencing the Motorcraft engineering number HJFS-24FP-X. A worn plug on these engines commonly causes misfire, rough idle, hesitation, hard starting, reduced fuel economy and misfire check engine codes. Double platinum electrodes provide long, erosion-resistant service life, and the plug ships pre-gapped to Ford's factory specification, with one plug fitted per cylinder. Torque to the factory value using care to protect the aluminum head threads.
