What is the consensus as to the best carbon box between BW and Evolve version? Are they any other manufacturers I have missed out?

The BW comes in 120mm and 200mm but the Evolve version does not specify.

Honestly I wasn't told specifically why from Epic Motorsport, but I'm sure the man has a valid point. He tunes TONS of S54's and has by far the best results. He just said "I'd save up and get a proper BW airbox" haha and I heard from pple that BW box is top notch. But then again, I ditched the airbox/cam idea.. for me it's not worth it, I can use that money towards a supercharger for my second Z4M soon to come hahaa

I was going for Eventuri, now I’m unsure. Any data would be appreciated Z4M_GT3
Ross not sure if this helps as I dont have experience with AFE or anything else but I have the Eventuri setup and I am happy with it. It looks great in place and I believe that it actually smoothed out the throttle response a bit. I cant say that i noticed any HP or torque gain or loss for that matter, but it looks and sounds good.
From what I've read on this forum the eventuri is a very nice intake and beautifully constructed. It really looks great in the engine bay and fits the quality and precision of an M engine. Some say it's not quite as loud as the AFe but close. It's not open to the heat of the engine, so that's a plus. But I haven't seen any dyno comparisons of the two. For looks, I think the eventuri has it. For performance, idk, it may be a wash. (Someone chime in here if they can say one is better than the other.) For sound, the AFe is a little louder. For price the AFe is around $500 while the Eventuri is close to $900.
