But be aware, RS4 MAF signal in original housing is very bumpy without airbox or venturi before it.

Thank you! We've been using RS4 MAFs for a long time in forced induction BMW setups and I found Vibrant filters to work really good even without an additional airbox.

This is log without any air filter or airbox, this thing betwen 3000 and 4000 rpm is turbo surge (tipical for K04-064 turbo) But still rest of RPM range whole time signal is bumpy. When I put air filter with ventury that signal is okay. But don t have any log in this moment |
