Recommendation compressors Z 4 2,5 ??? Hello, wanted to ask about your experience with compressor modifications on the Z4 (G-Power,Infinitas …..). Have a Z4 2,5 l,was last at Infinitas and I looked at this time was also everything great only at G Power I get 5 Ps more for a smaller price.Infinitas gives however 4 years warranty. And if you decide for a compressor it should be the best.Hope you can help me further. P.S.: The new 235 Ps variant of Infinita It was a little too little for me!
