BimmerWorld Silicone M50 Plenum Adaptor Kit

Looking for more top end performance from your S52 or M52?

Our M50 plenum adaptor kit is the easiest and least expensive way to install a higher volume M50 intake manifold on your S52/M52 engine. These OBD2 engines came with a narrow, low volume/high velocity plenums designed to increase low end torque while sacrificing high end horsepower (essentially a street tuned plenum). By incorporating the larger, higher volume M50 manifold you can expect an increase in upper rpm performance while only compromising low end power slightly. The kit includes all necessary hardware and instructions for a complete installation.  This is a thorough kit, but this is an involved project and mechanical experience will be needed and some tweaking of parts for your specific install may be required.

Kit includes:

• Silicone oil separator/idle valve adapter boot w/ vacuum line*
• Fuel rail adaptor plates and hardware**
• Oil separator to valve cover hose
• Throttle body adapter and seal
• Oil dipstick bracket with hardware
• Vacuum line with T-fitting
• Plenum gasket set
• Hose clamps

Applications:

• '96-'99 E36 M3
• '96-'99 E36 328is (2 door)
• '96-'98 E36 328i (4 door)
• '97-'98 Z3, 2.8l
