2002 BMW Z3..2.5i

[TOTE]

I would like to know how to get the most HP for my 2.5i. It is a 2002 Roadster

There are supercharger kits available if you want to spend as much money as the car is worth. Otherwise, I have heard, CAI, exhaust, headers, get a very small gain but cost a lot altogether.

Not worth the effort and expense, use it to spend on fuel and regular service work.
