Hi X5 FANS;
I had a question....I got a 2002 3.0 X5... ( No sports pkg)
I have 17inch factory rims and I just upgrade my wheels to 20.
It seems like that I am not getting the same power that I used to...
Do you guys know anything that can help me get my horsepower back? Will this hurt my engine? It seems like I am towing something!
How bad this will effect my gas millage?
It looks great, I just don't want to hurt my engine...

Thanks for your feedback very much
