ok couple of e30 m3 q's for you tech heads?

[koolz]

ive got an e30 m3 convertible and i was wanting to do a few mods, so what i wanna know is:-

whats better? a panel filter or a cold air induction kit, and im talkin about a proper air cone like a pipercross viper or bmc style one that has either a carbon fiber or metal casing to keep the hot air out?
which should i buy?

whats better? an alloy or steel strut brace?
whats better? a single bar or double bar strut brace?
whats better an ajustable strut brace, a 3-piece brace with hinges, or just a normal one-piece bar strut brace?
ive found that sparco do two strut brace's for the e30 m3? steel one at Ԛ£45.74(but its a nasty red colour and 1-piece) or an alloy one at Ԛ£92.24 (but its 3-piece and nicely polished)
which should i buy?
so experts help me out plz.

Cold air feeds are a waste of time on these, K&N panels are just not good for the engine. Pipercorss things cost around Ԛ£250, put that towards some proper engine tuning.

If you want more power then get a set of uprated Cams and a remap + bigger throttle bodies if you have the 45mm ones. Anything after that will be stand alone management with carbon firbe airbox (AlphaN).

Strut brace at front good idea. Look for a second hand Eibach one as they dont make them anymore.

Generally the more pieces its going to have the more flexible its going to be.

hi
i second sals comments
leave standard air box alone
unless you are going down carbon airbox/plenum and ecu route

strut braces are superb addititions
ive just ordered one of these but just the front one



its made by weichers
