EGR Coolers

EGR Coolers & Exhaust Gas Recirculation Parts

EGR coolers reduce the temperature of recirculated exhaust gases before they re-enter the intake manifold, lowering combustion temperatures and reducing NOx emissions. A failed or clogged EGR cooler can cause overheating, white smoke, coolant loss, and reduced engine performance — making replacement critical for diesel truck reliability.

OneFastShop carries EGR coolers including OE-replacement EGR coolers, upgraded heavy-duty EGR coolers, EGR valve assemblies, EGR gasket kits, and direct-fit replacements for Ford Power Stroke, Chevrolet/GMC Duramax, RAM Cummins, and other diesel platforms where EGR cooler failure is a common maintenance concern.

Every EGR cooler at OneFastShop ships brand-new with manufacturer warranty coverage. Whether you're replacing a failed EGR cooler on a diesel truck, upgrading to a heavy-duty unit, or servicing the EGR system during routine maintenance, OneFastShop has the part.
