Spark Plug
- Description:
This is a genuine Ford Motorcraft SP-580-X iridium spark plug, the ignition part that delivers a high-voltage arc between its fine-wire center and ground electrodes to ignite the air-fuel charge, firing once per cylinder each combustion cycle. It fits Ford 3.5L EcoBoost twin-turbo V6 engines, primarily 2011-2016 F-150 along with Expedition, Navigator, Taurus SHO, Flex and Explorer Sport 3.5L EcoBoost applications, so confirm the engine and build date for your vehicle. On these boosted engines a worn plug produces misfire under boost, rough idle, hesitation, hard starting, reduced power and fuel economy, and a check-engine light. The iridium center electrode resists erosion at high cylinder pressure and holds a precise gap, and the plug ships pre-gapped from the factory. In the Motorcraft catalog this is service plug SP-580-X, model code CYFS-12-YT4X, and it supersedes the earlier SP-534. Replace all six plugs together, start each by hand to protect the aluminum threads, and torque to the Ford-specified value on a cool engine.
