The Cummins ISL/QSL EGR Cooler from Bullet Proof Diesel features the latest, patented 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: 4990739, 4955485, 4955485NX 4955485RX, 4352253RX and 4352444RX. Please verify prior to ordering, but this EGR Cooler should fit all 2003 through 2018 Cummins ISL, ISC, QSL & L9 engines.
