The Bullet Proof Diesel H-Core EGR Coolers are designed to provide durability, reliability, and longer service life for Cummins diesel engines. The EGR coolers feature patented H-Core technology, which was developed to resist the common causes of EGR cooler failure. The design allows for the natural expansion and contraction of cooling tubes inside the EGR cooler. The EGR coolers are available for Cummins ISB, ISC, ISL, QSL, and L9 engine platforms.
