Product Details

BMW's M52 & S52 engines were an improvement over the M50 and the S50, but featured an intake manifold with smaller runners to maximize low-end torque at the expense of high-RPM horsepower. Swapping the restrictive OBDII manifold out for the OBDI M50 manifold is a popular modification, but when the modification is handled incorrectly, it can cause vacuum leaks and a check engine light. This kit makes it possible to install the M50 manifold on an M52/S52 engine while maintaining OBDII functions like the factory cyclone-style oil separator. This kit includes a CNC-machined adapter with all hardware and gaskets include for a stress-free install, and it's totally reversible should you choose to re-install your stock manifold. To complete the install, an modified fuel rail cover (ES3028165) is also available.

*May require modification to the ICV breather tube.*
