About Sinister Diesel
Sinister stands for everything diesel and they have made a name for themselves manufacturing some of the highest quality diesel engine components in the industry. The Sinister Diesel brand was born out of an idea from the founders while working on one of their own trucks. What if they started their own diesel performance business manufacturing and selling high quality air intake, fuel, and engine components? That idea transpired into the Sinisterl Diesel we know today. In order to make sure that when you popped the hood, you could easily distinguish a œSinister branded part from other companies, nearly everything they manufacture is coated in their trademarked œSinister Blue. Whether you drive a Cummins, Powerstroke, or Duramax, they can outfit your entire truck with cold air intakes, fuel tank sumps, oil filtration, regulated fuel return kits, and so much more. If you're looking for quality performance parts at a great price, look no further than Sinister!
