End Your EGR Headaches

The Sinister Diesel EGR Cooler looks and fits just like a stock product, the only thing missing: the factory EGR cooler problems. We've taken the headaches out of EGR coolers by removing the factory material inside. To eliminate clogging, we replaced the factory material with stainless steel tubes that allow for better gas flow. This kit includes the EGR cooler, and the gaskets to keep everything sealed up.

NOTE: Not suitable for Cab & Chassis models. For the Cab & Chassis Cooler click here.

New Construction:
aFe EGR coolers are constructed from new stainless steel components. All connections are welded not brazed, for reliability.

Direct-Flow Design:
12-large diameter flow-through tubes resist clogging, resulting in extended life of the cooler. The heat exchanger tube wall thickness is more than twice as thick as the OE unit.
