I want to get a little more omph put of my old 1996 328i touring.
I've just PM Alpina527 about the M50 and BBTB upgrade, however have also seen several people talk about a Dave F air induction system, I couldn't see his contact details anywhere?
What other cold air indiction could I look at? Is it even worth it or should I just replace the stock panel filter with a better one?
Any other good modifications without going as far as turbos etc.
