BMW N57 / N57S EGR and Cooler Delete Kit

BMW N57 and N57S Exhaust Gas Recirculation Valve Removal and Cooler Bypass

Unlock dependable power and reliability on your 3.0-litre BMW diesel with our proven recirculation valve removal and heat exchanger bypass solution for N57 and N57S engines. By eliminating the restrictive exhaust gas recirculation path and its coolant-fed heat exchanger, you reduce intake charge temperatures, improve response and help protect the turbo and intake tract from soot build-up. It is a smart upgrade for drivers who want cleaner airflow, stronger performance and fewer failure points.

• Lower intake air temps for more consistent power delivery
• Helps prevent carbon and oil deposits in the intake manifold and on the compressor wheel
• Removes a known weak point that can cause coolant issues
• Improves reliability by simplifying the system and reducing potential leak paths
• Great base for tuning, remaps and further performance upgrades
