New Performance Air Filter - BMW Forum

nookatee · 02-01-2005, 12:44 PM

Hello,
I've found this post tremendously helpful. It's very nice to find some knowledgable people who are willing to help out. I just bought a '93 BMW 325i. i totaly love it and want to start playing. I think first i will add a new higher performance air filter. Does anyone have any suggestions or insight from experience about a good brand. I know I put a K&N filter in my old '91 audi 90 quattro, but that didn't seem to increase horsepower or efficiency (or maybe just negligibly), so I know that these types of filters just don't have much of an effect on some cars. So, I'm hoping someone could tell me if a K&N filter would be worth it or should I just save up for a bit and throw in a whole CAI. Let me hear your thoughts. Thanks.
Ramy

bag the air filter idea and get a cold air intake...

how difficult is it to install a new cold air intake? i've never done it before.

jrhaile · 02-01-2005, 01:23 PM

very easy to do and most cais come with very good instructions...

Fairly straightforward. Unless you have ellipsoids or one of those three piece CAI. Other than that, its a straight bolt on. I think that if you could change your oil, you can put in a cai.

what effect will a CAI have on my exhaust system. would that need an upgrade too?

jrhaile · 02-01-2005, 01:33 PM

won't need an upgrade but everyone always says to chip your car, intake it and exaust it. best three mods for e36s

what kind of horsepower do you think a CAI will add and how will the gas mileage be affected?

jrhaile · 02-01-2005, 01:39 PM

a cai isn't as much as some will say. to be honest, maybe 5-8 at the most and that's MOST. gas will probably improve some too. more air is good :P

any thoughts on brands to look for? AFE, Vibrant, AEM? Does K&N make one? anyone know of a good place to buy?

What are all 3 worth?

Chip = 10 - 15 BHP?
CAI = 5 BHP?
Exhaust = 5 - 10 BHP?

So is it 20 - 30 BHP? Is this right?

I have seen it said that a chip and M3 Cam package is worth 30 BHp as well; would all 4 be worth 40 - 45 BHp together?

Anyone been to the Dyno?

Hey docrobot, are you near Medicine Hat?

dinan or cosmos...

every so often 1 or 2 of these will pop up on ebay! but they go fast!

Cold Air Intakes and Chips really seem to be the hot topics and if you do a search here you can learn alot.

I have been looking at the Conforti CAI that is on Turnermotorsport.com, also there is one on activeautowerke.com that looks good., and there is always the ECIS CAI ecisbmw.com. I would look at ebay but not even consider the ones that you can get for like $30-60. Although $350 for the Conforti one is a little high.
