filter

Je cherche à remplacer mon filtre.

Des préférences ?

Il a fait une recherche rapide et n'a pas trouvé de comparaison des résultats.

MS ? AA ?

J'ai acheté un K&N 55 sur Amazon il y a quelques mois. Aucun sens de payer 100 $ + pour un

AA !

Merci les gars

Arrêtez-vous, nous les avons en stock.

ight ill see if i can run by this week.

KN actually has shown loss of power on other bimmers and by far has the worst filtering of any aftermarket ones.

Its a no brainer to go with BMC, MS or AA green filters. All about 100 bucks. If saving 40 dollars by buying a kN instead is important to you, then you should not be driving a m3

I'd love to see your evidence for your poor filtration accusation. The used oil analyses for my 350z with a k&n filter always showed very low silicates indicating good filtration.

Beyond that, your statement doesn't make sense to me. How can it make less power (i.e. flow less) AND produce poor filtration? I highly doubt that. Seems to me it's either got to be one or the other.

O rly? maybe the biggest filter company should close their doors and i should sell my m3 then because I prefer to spend my $$$ smarter

I did not mean on this car but there is some other cars with info floating around that KN lost some power. Ill see if I can dig them up. Biggest does not always mean best. Remember they also advertise 15-20hp gains and people buy into this. People will buy whatever they are told if marketed correctly

^That was aFe for the 350Z. The claimed ridiculous gains for their intakes for the 350Z yet people don't seem to have an issue with them here.

I just think it's a little reckless to make claims like that when people use threads like this to make decisions about what to buy.

I personally think the noise that the aftermarket filters make is awful.

I'm probably going to take mine out. It might sound cool on a race car but on a street car it sounds like shit... there is a faint rattle rattle rattle under acceleration.

Mine is an AA btw, but they all do this as far as I know.

interesting... anyone else hate the noise?

I think a lot of people like it because it's a noisemaker but personally I find it cheapens the experience a bit. Maybe I'd like it on a race car but not on my street M3. Here's 2 links to some discussion:

Loss of power? From a filter??
K&N has an average filtration efficiency of 98.69% vs stock paper (same as an AFE oiled filter). These averages vs stock don't vary that much between the top brands.

I personally like AA green filter the best. If has an incredibly solid body which is less prone to the dreaded rattling.

My AA emits a rattling noise. With the filter, you can hear more of the engine's ITB's. It doesn't actually "rattle" in the airbox, I don't think.

Resonance instead of rattle maybe?

I haven't noticed any strange noises from my K&N filter. When are you guys hearing these noises?

Same with my K&N...it in there really tight. Put about 4K miles on it so far and no complaints
