Sinister Diesel Master Cylinder Cap

For 1999-2016 Ford Powerstroke

March 2019 Products, News
Sinister Diesel MFG. is releasing a new Master Cylinder Cap for the 1999-2016 Ford Powerstroke. OEM plastic factory caps have a reputation for cracking or becoming brittle over time. Sinister Diesel’s cap won’t crack due to stronger billet aluminum material and the added hand grips make this part easy to screw on or off.
It really finishes off the look under the hood. These caps are anodized Sinister Blue with a laser-etched logo to finish off a Sinister engine look.
