Installed the GruppeM intake on the car for a while now, and man is it some serious eye candy under the hood. I did not get the chance to dyno the car yet, but can definitely feel some slight pull, more noticeable though is the noise improvement sounds deeper more throuhty, but ofcourse will eliminate the oem valved system. I have attached some before and after sound clips hope everyone enjoys.

Love mine, what filter did the gruppe M come with?

 

Yeh they are amazing, they kept a K&N filter, didn't know there is more than one filter option

 

Mine is a rebranded “blitz” so it came with one of their stainless mesh filters. Way too small IMO. I put a K&N on it.

 

Sounds great. You can really hear the difference. Maybe, some cabin acceleration videos would be nice. I also have the K&N velocity stack filter (oiled).
