I have a 1999 M3 intake plenum in mint condition no cracks. The unit itself has 24,000km on it when it was pulled of the car. First person to offer me $60 takes it.

Would there be any advantage to using this plenum as apposed to the stock 325i m50 plenum?

What year is your car ?? If its an old model OBD 1 then stick with yours. Much better flow by far than the stock M3. I actually did and OBD 1 conversion to a 325i intake plenum. They flow much better. Bigger plenum design.
