Filter really wont get you any noticable power.

Do all modifications before getting the car tuned. You'll be wanting a remap.

Headers might be something to look into.

A good filter does make a difference, but I agree with james, if you are going to get the car professionally remapped then get it done after any mods so the remap takes maximum advantage of any changes.

Another point. Don't bother with the big mushroom filter, it's more expensive and really wont benefit a non boosted motor much over the panel replacement.

The biggest noticeble gain for an e46 is getting rid of any 2 into 1 or x-pipes.

These are installed from factory in different exhuast configuration (depending on OEM options ticked) to remove noise at the expense of top end power.

I removed this from my old 330 when I installed a supersprint exhaust system and gained noticible top end because of it. Still had a stock filter.

Dig up a couple of threads from 'Wayney' he has done all of these sorts of mods on his e46 328i including before and after dyno plots.

another thing to look at is if your car is over 130ks looking into your VANOS seals
