The Z3 Gruppe M intake is different to any other e36 era Gruppe M intake I've seen. The shape is different.Lol. I will. Do you know if the e36 version can be cajoled to fit a Z? Sadly I think there must be lots of these things hiding on back shelves in shops and in people's garages.
After some bling and some sound without losing hp. Currently on stock box after running a pod with heat shield for a while then looking at the intake temps in torque app...
This weekend poking around in there I found the headlight duct has a removable kind of circle thing at the bottom exposed to under the bumper so might just run an air feed from there for more flow and stay stock.
Still would like that intake roar though..
