- Description:
This is a genuine Ford Motorcraft SP-594 iridium spark plug, the ignition part that fires a high-voltage arc between its fine-wire center and ground electrodes to ignite the compressed air-fuel mixture, once per cylinder each combustion cycle. It fits a broad range of 2015-2026 Ford EcoBoost turbocharged engines, including 2.0L and 2.3L four-cylinder EcoBoost and 2.7L and 3.0L EcoBoost V6 applications across models such as F-150, Bronco, Ranger, Edge, Explorer, Aviator and Continental, so confirm the specific engine for your vehicle. On boosted engines a worn plug brings misfire under load, rough idle, hesitation, hard starting, reduced power and fuel economy, and a check-engine light. The iridium center electrode withstands high cylinder pressure and holds a tight, stable gap, and the plug arrives pre-gapped from the factory. In the Motorcraft catalog this is service plug SP-594, model code CYFS-12Y-RT3, superseding earlier SP-542 and SP-578 numbers. Replace the full set, start each plug by hand, and torque to specification on a cool engine.
