Cummins Exhaust Gas Recirculation (EGR) Cooler Upfit Kit

Managing the high temperatures that compromise emissions components is the most effective way to keep your engine in compliance. This Cummins Exhaust Gas Recirculation (EGR) Cooler Upfit Kit is an engineered update for your EGR circuit, designed to lower exhaust gas temperatures before they enter the intake. Dropping these combustion temperatures helps keep NOx levels within legal limits and protects internal engine parts from thermal stress. Unlike older configurations that often develop internal cracks from constant heating and cooling, this reinforced assembly is built to withstand repeated thermal cycles without leaking coolant into the exhaust. Installing this Cummins 4376527 upfit kit during an emissions service helps prevent the white smoke and fluid loss that lead to a failed inspection and keeps your truck on the road under heavy loads.
