Eventure or Gruppe M airbox for Z4M

[RWDKurt]

Thanks for the detailed feedback Shaun - all being well, I will soon be going down the same route!

I have had both and currently have a Gruppe. I sold my Eventui because I felt the noise was too loud across the full range of revs, and didn’t think the sound was that great. At the time I was using the car a lot and the noise got a bit much for me, (always loud) Once I went back to a standard filter I was much happier. Now that I use the car less I decided to have another go but with a Gruppe. Personally I think the Gruppe is a much nicer sound, mellower not as rattley and only seems to start making its presence felt above 3k revs. The disadvantage of this of course is that now I always have to have my foot flat to the floor, so budget in fuel costs if you go down this route :lol: Of course these are only my opinions and as there is probably 2 years space comparing the Eventui to the Gruppe and my memory might be playing tricks on me, however I sold the Eventui and have no plans to do so with the Gruppe. I’m sure many will disagree with me and I’m sure if you buy either you will be happy and if you buy second hand you won’t lose money when you come to resell.

Gruppe Ms arent as hard as people seem to think to get hold of there has been one for sale almost every week recently.

One of those things, costs a lot looks nice for limited gain. If you add an airbox and an exhaust it will benefit from being mapped to take advantage of the additional airflow. By the time you've got a good exhaust system and the airbox fitted them and then mapped probably looking at 2k+ for small hp gains. If its just sound and engine bling then

Im on the fence currently. Everything is getting super expensive, I paid £800 for some aero skirts recently that need painting and £350 for an OEM strut brace so again can say the same for those items too.

Ive heard positives and negatives, people seem to keep them short term but some of the longer terms I've heard of MAF issues? Might be wrong there.
