Sinister Diesel

Sinister Diesel makes upgrade parts for diesel trucks, and the listings here are mostly for Powerstroke engines. The main groups are cold air intakes, intercoolers and charge pipes, exhaust tips, and a few fuel and coolant parts such as a fuel filter conversion kit and a turbo coolant feed line.

Because the brand lists no vehicle names, fit is written into the titles by engine: the 7.3L, 6.0L and 6.7L Powerstroke, with model-year ranges such as 2011 and newer or 2017 and newer. Match the engine size and the year range together, since a 6.7L intake from one generation will not suit another.

Charge pipe kits replace the cold side or hot side pipes that carry compressed air between the turbo and the intercooler. Hot side and cold side are sold separately in some years, so read the title carefully. Cold air intakes here are listed per engine.

There is also a universal ceramic-coated stainless exhaust tip. Titles list the inlet and outlet size, for example a tip that goes from a smaller pipe to a larger outlet, so measure the tailpipe first.

Browse air intakes and intercoolers to compare with other makers. Each product page lists the years, makes and models it fits, and the vehicle selector shows only parts for your truck.
