Spark Plug
- Description:
This is a genuine Ford Motorcraft SP-550-X iridium spark plug, the ignition component that fires a high-voltage arc across its fine-wire center and ground electrodes to ignite the compressed air-fuel mixture, once per cylinder every combustion cycle. It fits a broad range of 2012-2025 Ford EcoBoost turbocharged engines, including 1.5L, 2.0L and 2.3L four-cylinder EcoBoost and 3.5L EcoBoost V6 applications across models such as F-150, Mustang, Explorer, Edge, Escape and Focus, so confirm the specific engine for your vehicle. Because turbocharged engines are hard on plugs, worn units bring misfire, rough idle, boost-related stumble, hesitation, hard starting, reduced fuel economy and a check-engine light. The iridium center electrode withstands the higher cylinder pressures of forced induction and holds a tight, stable gap; the plug arrives pre-gapped from the factory. In the Motorcraft catalog this is service plug SP-550-X, model code CYFS-12Y-PCTX, superseding earlier SP-527 and SP-537 numbers. Replace the full set, start each plug by hand, and torque to specification in a cool head.
