Mike,
I have just bought a 2012 BMW M135i and want to buy the following
JB4 and intake
How much is it for both and is the delivery free? Can you buy them in the UK or do they have to be shipped from USA?
Does the JB4 give me all the maps and options via the steering wheel the M135i too? Stage 2 I believe
Will the intake give me more performance? Is there a map that takes it into consideration apart from map 1
Thanks lee
