Bullet Proof Diesel has long been the innovator that put reliable and EGR Cooler together in the same sentence. We started with the Ford 6.0L square EGR cooler and we have not stopped innovating since. Bullet Proof Diesel's reputation for building tough, capable and functional components is well known. The Duramax EGR cooler is no exception. Buy yours today and find out with thousands of our customers already know about Bullet Proof Diesel products.
This LML EGR cooler features our patented H-Core technology. What is H-Core? Well - it's cool and it's something that makes EGR coolers VERY reliable! It works by using twisted sets of tubing in place of traditional straight or rigid tubes. By twisting the tubing, they are able to flex and move - greatly reducing stress on the bulkheads and seams. This also allows us to stack the tubing very close together, allowing for more tubing - and cooler EGR gas - than would be with traditional straight tubes.
Bullet Proof Diesel 6.6L LML Duramax EGR Cooler matches up with GM part number 12635707.
