About Sinister Diesel

Sinister Diesel, a home-grown Diesel parts company founded by Brian George and Michael Mitchell, both went for Diesel. Sinister Diesel changed the way it does business, and customers can call Sinister Diesel for technical advice on branding, components, installation and other aspects of its products throughout their purchase. For Sinister Diesel, real-time phone support was a very important part. Sinister Diesel had a number of very good partners in the industry, including H&S Performance, ARP, AFE, SCT, Bully Dog, MBRP, S&B and many more, which gave customers plenty of component options. And Sinister Diesel has its own production line. Founder Bryan believes that people who love diesel lifestyle are a bit rebellious, although not everyone lives a rebellious life. So Diesel parts were mostly a fashionable and 'Sinister' metallic blue, and the name Sinister Diesel was very much in keeping with the spirit of Diesel.
