Quality Parts, Fast & Free Shipping We have ordered from Sinister Diesel before and I know it is a website we can trust to order from, and the parts arrive in just a couple of days. If we have any questions, it is easy to reach a person in customer service and they are knowledgeable about the products we are purchasing and are able to answer any questions we have. Maybe there are cheaper parts available on the web, but you get what you pay for and these parts are quality! Thank you!

EGR DELETE 6.7 POWERSTROKE Bought the EGR delete for my F350. Super reasonably priced with very quick shipping. Very high quality and everything in the kit fit perfectly. Will definitely be buying more goodies from Sinister.
