Sinister Diesel 03-10 Ford Powerstroke 6.0L/6.4L Oil Filter Cap

Machined from a single solid aluminum billet, this Sinister Diesel oil filter cap is built to last. The factory plastic cap on your 2003-2010 Ford F-250 Super Duty with a 6.0L or 6.4L Powerstroke engine can crack over time. When that happens, you risk air getting into your fuel system, which can lead to hard starting or even damage your fuel injectors. Plus, a cracked cap can mean a fuel leak, and that's never a good situation on a hot engine.

This cap is a direct replacement for the OEM part but is far stronger. The solid aluminum construction means it won't crack like the original. It's also anodized in Sinister Blue to help resist corrosion. A practical detail is the 1/8th-inch NPT port, which makes it easy to tap into for fuel pressure testing without needing to remove the cap.

You'll get the oil filter cap and a new O-ring in the box, so you'll have everything needed for a straightforward replacement. It's a solid option to ensure your fuel system stays sealed and protected.
