Sure, this billet cap kit looks pretty cool when you pop the hood of your SuperDuty, but that's not the whole intention of it. Over time, the factory caps' plastic construction can fatigue and crack, but you know what doesn't crack? Billet, that's what!
You'll never again have to worry about cracking the factory OEM oil and filter caps on your Ford 6.4L Powerstroke diesel. The Sinister Diesel Billet Kit includes three precision CNC machined caps that won't crack or crumble after repeated heat cycling like the factory plastic parts can. They also feature an eye-catching Sinister Diesel blue or gray anodized finished to dress up your engine bay.
