The XDP EGR Race Track Kit with Hose XD199 is designed to remove and block off the Exhaust Gas Recirculation (EGR) system found on your 2013-2016 Dodge 6.7L Cummins engine. The addition of the coolant hose with the XDP EGR Race Track Kit allows you to re-route your coolant instead of just "blocking" the flow. This keeps your coolant flow from being interrupted, allowing your cooling system to function properly without the EGR cooler present. For off-road use only. Aftermarket tuning required.
