Rally Road Intake Manifold Assemblies

BMW enthusiasts seeking to elevate the performance of their M52 & S52 engines can now explore an enticing solution with this product. While these engines represent improvements over the M50 and S50, they come equipped with an intake manifold featuring smaller runners, designed to maximize low-end torque but at the expense of high-RPM horsepower.

Many enthusiasts opt for the widely adopted modification of replacing the restrictive OBDII manifold with the OBDI M50 manifold. However, it's crucial to note that mishandling this modification can result in vacuum leaks and trigger the check engine light.

This all-inclusive kit presents an effortless way to install the M50 manifold on an M52/S52 engine while preserving essential OBDII functions, including the factory cyclone-style oil separator. The kit includes a meticulously crafted CNC-machined adapter, accompanied by all the required hardware and gaskets, ensuring a seamless installation process. Notably, this modification is entirely reversible if you opt to revert to your stock manifold. For a complete installation, consider the availability of the modified fuel rail cover (ES3028165).

Kindly be aware that, depending on the application, certain modifications to the ICV breather tube may be necessary.
