Ford
Direct Bolt-In Replacement Ignition Coil Set
  • Fits 2004-2008 Ford 4.6L and 5.4L 3-Valve Modular Engines
  • Accepts Factory OEM Connectors
  • Hotter Spark for Quicker Throttle Response
  • Black Finish
  • Set of 8

    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.
    • Part TypeIgnition Coil
