The Cummins ISL/QSL-G EGR Cooler from Bullet Proof Diesel features the latest, patent-pending EGR technology. This new interior tube design makes the internal structure more forgiving, and thus allows this EGR Cooler to survive through heating/cooling cycles as well as thermal events long after most EGR coolers fail.

This EGR Cooler replaces the OEM P/N:  5347234, 5318560 and 4376312. Please verify prior to ordering, but this EGR Cooler should fit all 2003 through 2018 Cummins/Paccar ISL-G, ISL L9and ISQ engines.
