Bullet Proof Diesel’s EGR coolers are available for Cummins ISB, ISC, ISL, QSL, and L9 engine platforms.

The coolers feature H-Core technology that allows for the natural expansion and contraction of cooling tubes inside the EGR cooler — which reportedly limits structural failure that can occur at the end of the tubes, rupturing the EGR cooler and leading to possible engine component damage, according to the supplier. The H-Core construction also increases the surface area of the coolant tubes within the EGR coolers, making them more effective heat exchangers than other tubed designs, according to the supplier.
