I have a 328i Coupe on a R plate (1997) M52 I beleave if incorrected please let me now.
I have been told that there are six breathing modifications to be done. Can anyone help with them mods and more please.
If i change the inlet manifold with a bigger bore throttle body off a 325i this will give me approx 20hp and makes the car more responsive. Can anyone help out please.
