new to intakes, i have an 06 325i and am just looking for a noticeable sound difference. found this video on youtube and love how it sounds

just wondering on experience with either brand because i always heard k&n is one of the best but i can't find any videos of a k&n system in a bmw

Doesn't matter. Power, quality and sound-wise it will pretty much all be the same so you can either get the cheapest one or the one that you like the best. Enjoy your intake!

I have an Injen Intake with Amsoil filter. great sound but i cant clean the filter so i decided on getting a K&N filter (cone) to attach to the injen tubing and after about a day or so my check engine light came on. My car cant handle the K&N filter, i'm running to lean! i put the stock airbox back in and so far no check engine light. The k&n had a much deeper sound then the amsoil filter but too bad my car isnt able to handle the k&n. I have a 2007 328i. hope this helps. Cheers

really? first time i heard an issue like that are you sure you installed the clamps tight enough?, sounds like you have extra air leaking in some where

i have the afe intake. at first it felt like i had 300 hp extra under the hood. but when i got used to it, i started to feel that the car was not running smooth any more... but the sound is damn nice

Try it again. Something was disconnected or there was a vacuum leak. The filter will not cause your car to run lean, the computer will compensate based on the intake sensor to the correct air/fuel mixture.

If the sensor was unplugged or loose --- it'll throw a CEL light.
If there is a vacuum leak AFTER the sensor --- it'll throw a CEL light.

I will try the k&n again in the summer. For now I'm running stock.

I just recently installed the Injen Intake in my car. It definitely adds some nice sound and a slight performance gain as well.

Injen Intake +1

+1 KN

K&N Does not make a full intake only a drop in filter.

I personally have the Injen SP1121blk Short Ram and love it.

Drop in wont change sound, actual intake will.
