Sinister Diesel - EGR Coolers & Components

EGR Coolers & Components
The stock EGR cooler in your Cummins, Powerstroke, or Duramax-powered diesel truck is designed to recirculate up to 50% of your engine’s exhaust back through the intake to help reduce emissions during everyday driving. But when you’re demanding more from your truck, the stock EGR system can hinder performance and become a liability.

If you’re looking for the most reliable performance, while maintaining legal emissions, we have you covered with our fully TIG-welded EGR Coolers that are the perfect replacement for the notoriously weak stock components. For the diesel owner who’s looking for uncompromising performance, we also offer a large selection of complete EGR Delete kits that remove exhaust restrictions, free up power, and give you the competitive edge you need on the track.
