I know their 7.5 is well liked and recommended... 5" not so much... google around a bit and youll probably find some answers... use n54 vrsf intercooler and not Z4... it gets you better results...
intercooler is the same in 335i 135i z4 35i and is models... chargepipe is different and so are downpipes...

Alrighty, so I went with vRSF for both the intakes and Chargepipe BOV! I know you mentioned to go with the n54 intercooler, is that the 7.5” Stepped HD Competition FMIC? On their site there is an FMIC (7.5 HD specifically for the Z4, is it this one?
Also, with the vRSF catless downpipes has anyone had any issues with emissions?
