The only benefit you'll see on an E30 from a CAI is an increase in sound. The stock airbox is as good as it gets.

If PROPERLY heatshielded you can avoid LOSING power and if you've also added a chip and exhaust you will experience a tiny improvement in throttle response. This is a lot of expenditure for not much gain though so for all intents and purposes you're best off just replacing your stock filter regularly.
