The 6.0 Powerstroke EGR cooler delete kit allows removal of the EGR Cooler from the truck. Coolant flow is directed through the included pipe to maintain proper flow. Exhaust gas is kept where it should be, driving the turbo. A 20-30 degree drop in coolant temperature was common on our test trucks. On certain trucks this modification may set a check engine light, our custom tuner can eliminate this condition.
