to those that have mods on their cars - any issue with warranty work or scheduled BMW maintenance?
I have JB4 on its way and considering which air intake (recommendation would be appreciated too).
1 questions that got me a little confused
- aFe Stage 2 Sealed Air Intake vs BMS Dual Cone Setup, is there a huge difference in performance as aFe is $500 and BMS is only $100
Thanks!
