What BMW has M50 intake manifold?
What BMW has M50 intake manifold?
The M50 intake manifold (right) from the E36 325i and 3.0L M3 is a popular and inexpensive way to improve the high RPM breathing and power of the later 1996-1999 cars. The narrow intake runners on the 3.2L S52 (left) improve mid-range torque at the expense of choking the motor at high RPMs.
How do I remove the M50 manifold?
Steps required to remove a BMW M50/M52/S50/S52 Intake Manifold
- Step 1: Remove the intake tubing.
- Step 2: Remove the vacuum lines and electrical connections on the upper portion of the manifold.
- Step 3: Remove the throttle body coolant lines.
- Step 4: Disconnect the crankcase vent line.
What is M50 intake manifold?
The M50 manifold is a simple design using long and wide runners and a shared plenum with the throttle body in the middle. This helps distribute air evenly between cylinders and allows the engine’s air reverberations from the valves opening and closing to even out at high rpm and assist with flow into the engine.
What car comes with M50?
In September 1992, the M50 was upgraded to the M50TU (“technical update”), which was BMW’s first engine to use variable valve timing. Called single VANOS by BMW, the system adjusted the phasing of the intake camshaft….BMW M50.

What is a DISA valve?
The DISA valve (also known as the air adjustment unit) controls the path of air through the plenum, regulating the intake manifold pressure to provide greater torque around town and more power at higher revs.
What car did the M50 come in?
BMW M50
The BMW M50 is a straight-6 DOHC petrol engine which was produced from 1990 to 1996. It was released in the E34 520i and 525i, to replace the M20 engine. In September 1992, the M50 was upgraded to the M50TU (“technical update”), which was BMW’s first engine to use variable valve timing….BMW M50.

Is the M50 engine good?
Much like its successor, the M52, the M50 engine is considered to be bulletproof. With very strong internals, the engine blocks are able to deliver outstanding longevity with proper maintenance and care. Still to this day, the M50 is known as one of the most reliable BMW engines ever built.
Is the M50 reliable?
How do you replace intake manifold on BMW M50?
The rear tab that used to hold an O-2 sensor connector will need to be bent out of the way to clear a fuel rail mounting point on M50 manifold. A bracket will need to be fabricated to hold the fuel rail in place. I simply used some piece of scrap metal I found in my toolbox and drilled two holes in it.
Where are the manifold brackets on a BMW?
Both support brackets and the wiring harness bracket are mounted to the engine. Bolt up two OBD-I manifold brackets to your block. Part numbers for the brackets are 11-61-1-735-265 and 11-61-1-738-759. Please note how the new brackets mount to different locations on the block.
What are the parts numbers for an OBD-I manifold?
Bolt up two OBD-I manifold brackets to your block. Part numbers for the brackets are 11-61-1-735-265 and 11-61-1-738-759. Please note how the new brackets mount to different locations on the block.
Where does the air pump connect to the intake manifold?
I cut a slice out of an OBD-I hose 13-41-1-738-185, trimmed the ridges and installed a T-fitting into it. Your oil separator and purge valve hose will connect to this vacuum source. The air pump control valve hose will connect directly to the connector 11-61-1-738-929 that clips into the back of the manifold.
