Hello, since May 2004 I count myself among the lucky ones who are allowed to drive a Z4 3.0. I have been following this nice forum for a while (irregularly), but to my question I have found nothing about the search. After obviously higher motorized Z4 variants still wait for an indefinite time (new 3l with 258 HP possibly soon, Z4-M is in the stars), our sweetheart should get a small performance cure in the spring. r, namely the smallest expansion stage “NOWACK auto+sport Motorkit EVO II” with power increase approx. 25 kw / 34 hp torque increase approx. 30 NM – NOWACK exclusively sports camshafts (EVO I) – Optimization of intake air guide (RAM-air) – sport air filter with increased air throughput – Optimization of engine software to above mentioned tuning components (for switching vehicles incl. speed band extension to 7,000 rpm) – V-max. suspension (V-max. > 250 km/h) – assembly costs: EUR 2.780,00 Hat any of you have already had experiences with Nowack, possibly even with this or another performance upgrade kit? I’m curious. Greetings Prian
