Bullet Proof Diesel 6700012 Front EGR Cooler

The Bullet Proof Diesel 6700012 Front EGR Cooler is a superior direct-fit replacement for the leaking EGR cooler in your 2011-2016 GM 6.6L Duramax LML. This EGR cooler features Bullet Proof Diesel’s exclusive H-Core technology that twists the coolant tubes inside the cooler. Twisting the tubes inside the cooler greatly reduces stress on the bulkheads and seams. The twisted tube core also provides more surface area over straight tubes for more efficient cooling of the exhaust gasses.
