The 3-valve modular Ford engines are known for coil-on-plug failures that throw a misfire code and leave the truck running on seven cylinders. Replacing all eight at once is the practical fix. These coils mount in the factory locations on 2004-2008 4.6L and 5.4L 3-valve engines and accept the OEM connectors, so the swap is a plug-in job.

MSD 55138 Ignition Coils Features:

Complete set of eight coils for 4.6L and 5.4L 3-valve modular engines.
Direct bolt-in replacement that accepts factory connectors.
Improved materials and winding ratios for higher spark energy.
Restores throttle response and smooth idle.

Street Fire Coils mount in place of factory coils and accept OE connectors. Spark energy is increased thanks to improved materials and more efficient winding ratios that were selected by MSD engineers.
