Z4 B48 20i Engine Tuning & Mods
Hi Guys,
So i just recently bought my Z4 20i, and i would like to know the options i have for engine tuning. Does the JB4 work on the 20i ?
Also, how come there are no M Performance parts for the car ? Are they planning on releasing them or no plans were made for it at all ?
Appreciate your help guys.
