I enquired at my local performance garage about changes I could make to my
2004 M3, I knew I'd read that a simple replacement air filter could make a
difference in performance.
The guy has told me a Typhoon induction kit is available for my car priced
at 238ukp but he can get me 20% off that.
Has anybody fitted one of these and if so are they worth it?
I'm happy enough with the performance of the car, just think it would be
nice to be faster than a "standard" M3.
Thanks in advance
