Spark Plug
- Description:
This is a genuine Ford Motorcraft SP-546-X platinum spark plug, the ignition part that arcs high voltage between its platinum center electrode and ground strap to ignite the air-fuel charge, firing once per cylinder each combustion cycle. It fits 2004-2008 Ford 3-valve modular engines, primarily the 5.4L and 4.6L 3V V8 and 6.8L 3V V10, used in F-150, Expedition, Super Duty F-250 through F-550, F-53 motorhome chassis, Lincoln Mark LT and Navigator, so verify the engine for your vehicle. Worn plugs on these engines cause misfire, rough idle, hesitation, hard starting, reduced power and a check-engine light. The platinum electrode resists erosion for extended life and the plug is pre-gapped at the factory. In the Motorcraft catalog this is service plug SP-546-X, engineering code PZK14F, and it supersedes the earlier SP-515. On these 3-valve engines apply the specified anti-seize and torque procedure carefully and remove plugs only on a cool engine to reduce the risk of thread damage.
