The Dirty Diesel EGR Upgrade is a critical modification for high-performance 2011–2016 LML Duramax builds. Manufactured right here in Canada from high-grade billet aluminum, this race kit is designed to completely replace the entire factory EGR system. By removing the restrictive and failure-prone OEM cooler, you eliminate the risk of soot contamination and coolant leaks.

Our design allows for a comprehensive installation (approximately 6–8 hours) without the need to remove the intake manifold, saving you time without compromising on quality. This kit facilitates faster coolant recirculation for lower overall temperatures and provides the clear exhaust path your turbo needs to perform at its peak.

Part Number: LML-EGR-A003
