2004.5-2005 Duramax EGR Cooler (SD-EGRC-LLY)

Fits

Sinister Diesel has reinvented the Exhaust Gas Recirculation (EGR) cooler with the SD-EGRC-LLY EGR Cooler that has the exact same fit as the factory GM unit! When the internal brazing cracks and fails in the factory EGR Cooler it will allow coolant to be sucked into the intake manifold. From the manifold, it enters the combustion chamber and usually results in a blown head gasket or hydro-locked motor with a costly repair bill for thousands of dollars!

If you're tired of clogs and the possibility of a catastrophic failure with the stock 6.6L LLY Duramax EGR cooler, or if you just want to prevent future headaches from unnecessary maintenance, protect your investment in your truck with the upgraded SD-EGRC-LLY EGR cooler from Sinister Diesel. Instead of the narrow internal cooling fins with brazed connections, they assemble each 6.6L LLY Duramax EGR cooler using high-flow stainless steel tubing with quality TIG welds. Following that, they then pressure-test each unit to ensure it holds the reliability that a stock unit can't match.
