The EGR cooler lowers the temperature of recirculated exhaust gas; cracked coolers are a common cause of coolant loss, white smoke, and overheating on engines like the Ford Powerstroke 6.0L and 6.4L. We supply OEM-brand EGR coolers built to OE specifications, many with no core charge and free shipping on orders over $1,000. Match the cooler to your engine's OEM cross-reference before ordering.
