Sinister Diesel Billet Blue Fuel Filter Cap 08-10 6.4L Ford Powerstroke

Isn't it great when you can add a stylish upgrade to your truck that also serves a purpose? The stock plastic fuel filter cap is known to crack, allowing air to enter into the fuel system, which can lead to cavitation. Upgrade your fuel cap with this great looking, billet construction cap from Sinister.

Constructed from a single solid aluminum billet, the Sinister Diesel Fuel Filter Cap is far stronger than the OEM plastic cap and anodized in a stylish blue with Sinister Diesel branded engraving.
