Schrick Performance Intake Manifold-2.8L Z3 &  M Roadster

On the M52 engines BMW uses one intake manifold design for engine capacities from 2.0 to 3.2 liters (U.S. Models 328, M Roadster, and 3.2L M3). These manifolds produce excellent torque but in the larger capacity engines they don't supply sufficient flow at higher rpm. This is especially noticeable on engines modified for increased power.

Schrick's goal was to design a manifold which would provide increased performance at higher rpm's without sacrificing low end torque. They accomplished this using 3D-CAD software to optimized flow at all rpm ranges. The new manifold design includes changes in the intake runner diameter, length and shape, the air plenum chamber has been enlarged for greater capacity, and the injectors have been moved closer to the ports.

Schrick dyno tests on the 2.8L engine showed a 14HP increase with no other modifications. A larger increase is expected in the 3.2 engines. Further gains are possible with the computer programming, performance cams, free flow exhausts, cylinder head modifications, etc.

The Schrick manifold is made with a removable plenum cover which allows access for porting and polishing for further air flow increases.

The manifold is a direct bolt-on upgrade for the 2.8 and 3.2 liter engines.  Installs in approximately 3 hours.
