Sinister Diesel 2007.5-2010 GM Duramax 6.6L LMM Replacment EGR Cooler

This 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.

Sinister Diesel Upgraded EGR Coolers are direct OE replacement parts and do not alter or render useless any emissions equipment including the factory EGR system.* $140 Core Charge will be ran on your credit card per cooler and credited once we receive your old egr cooler within 30 Days.
