I had a gruppe m induction system on my z4m. Sounded amazing () but when I swapped it back to stock to sell I realised how much torque I was missing!

I read previously that the gt86’s stock air box was pretty good so I’d guess m division know what they are doing as well.
These things probably only make sense in highly tuned situations by the sounds of your experience?

Makes sense, yeah the z4m also had a pretty good stock airbox with ram effect. I just did it for the CSL like sound and the CSL stock airbox is much more complicated with flaps etc
 
Pretty sure they want £1200 for that.

Oh GruppeM isnt german. Didnt know it was made in japan. Then its ofcourse illegal to use in germany :ROFLMAO::ROFLMAO:
 
The quality of some of the GruppeM kit for the Yaris was shocking for that kind of money. Weird, because they had a good rep for the BMW parts.
 
10 horsepower increase with no other mods, as per the comments.
