    Hi, i own a 325se and i bought it with a KN cone filter already on it. I have heard that this will be restricting the performace instead of increasing it. Is this the case? Cheers

    After readinf some of the post regarding this, i believe most members think its better to go with a panel filter, and yes some do believe it decreases or doesnt make much difference in performance.

    lot of money to spend on something that isnt going to improve your beemer to be honest mate, all well and good on a 106, saxo, fiesta etc but with your cars power now you wont notice a lot of difference!

    im looking at getting a high flow panel filter to replace the standard on mine after speaking to a lot of very clued up guys on this forum! id say thats the best way to go!

    The forced air kits are very good as they are sealed, they dont draw in any hot air from the engine bay....

    They wont really give any more Hp but they do make the throttle more responsive...

    i agree from my previous car i had a cone on it and then changed to a green panel filter and IMO it was alot better and will be doing the same on the BM as soon as possible

    Panel filters in the standard airboxes are the best set up I've found as they draw cold air in from outside the engine bay.
    cone filters even with "cold air feeds" draw most of their air from under the bonnet where it's warmer air.
    this is more pronounced on N/A cars than turbo cars as most modern turbo cars have an intercooler of some sort where as a N/A car has no way of cooling the air once it's passed the filter

    What benefits do you see from a panel filter? Are K&N ones good? Would it increase performance/sound? Thanks

    I rarely need all the power from my 325. Fitting a K&N was done both for the sound (which is a lot louder in terms of induction roar) and aesthetics when the bonnet is up. I just like the look of them. Its the same reasonmy bike has 2 little ones on the carbs.

    I took on board the fact that it was a possibility the change would either give me no increase in power, or perhaps even give a slight decrease. But I didnt give a rat ass about that. It felt more responsive with the new filter, though I would be the first to admit that it may be the sound that makes it 'feel' better. But with a motor just on the shy side of 200 brake horse and driven around town a lot, I can stand losing a couple of those gee ups (if I did) to the acoustic improvements it definitely gave.
