Great products, I've bought a coolant filter kit and an aluminum degas bottle and love the quality!

Company Choice

High quality parts made in America.

Product Choice

It seems like the best quality for the fairest price. Why dig that far into a diesel truck just to replace it with low quality parts? Sinister diesel cares about that look of amazement when you get the box on your front porch.

I truly love it. I and my little brother plan on building up our diesels and he has a 97 dodge cummins and i have a 95 chevy 6.5 its nice to have a site that has both!

Product Choice

As i stated above me and my little brother wanna upgrade our diesels. Our stock air filters weren't cutting it anymore at least for my 6.5. He wouldn't replace his filter so i bought him an aftermarket one for his birthday just so he had to replace it if he didn't wanna feel like a jerk.

Company Choice

It was simple to order the parts i needed and all the reviews looked like you guys shipped fast
