Designed as an aftermarket replacement option for selected Ford, Mercury and Lincoln vehicles equipped with a compatible 3.0L V6 gasoline or flex-fuel engine.
The iridium-platinum electrode design is intended to provide a concentrated ignition point and consistent spark during normal engine operation.
🔴 4 SPARK PLUGS INCLUDED
🔴 REFERENCE NUMBER SP-511
🔴 CROSS-REFERENCE CGSF-22F
🔴 FOR SELECTED 3.0L V6 APPLICATIONS
🔴 CHECK OE NUMBER OR VIN BEFORE ORDERING
Compatible 3.0L V6 engines normally use six spark plugs for a complete engine replacement.
🔴 This 4-piece package is not a complete six-cylinder service set.
Please order the required quantity for your repair before beginning installation.
The fine center electrode is designed to create a focused ignition point for consistent starting and combustion.
A platinum contact area on the ground electrode is designed for stable operation during the plug’s normal service life.
The ribbed ceramic body helps separate the high-voltage terminal from the metal shell.
The sealing washer provides the required contact surface when installed in a compatible cylinder head.
