K&N Air Filter $39.63 on Amazon
Hi all,
Just an FYI for anyone looking for a drop in air filter replacement. Amazon.com is selling the K&N #33-2332 High Performance Replacement Air Filter for $39.63. It's eligible for free 2 day shipping if you have Amazon Prime (highly recommended and free for a year if you're a student). http://amzn.com/B000E5W9PA My '06 330xi is about to turn 50K miles. I figured it was time to replace the air filter. Enjoy!

I'm currently running an aFe Stage 2 (open box) air intake... you guys think it would be better to throw my stock intake box back on there and throw a K&N filter in there and take out the charcoal filter?
Right now, i'm not seeing any gains in power or whatever but it makes my engine louder and it's helping me out with +2 mpg... My thoughts... since i have RPI scoops, i'm thinking some of the rammed air is dissipated to other parts of the engine bay and not forced into the intake itself. With this, i'm thinking a stock intake box would receive more air from the scoops. K&N filter is good flow and taking the charcoal filter out just means less restriction... (kind of like the charcoal "brita" filter in your sink... it's still water and it's still drinkable without the filter, but it tastes better) |

The enclosed system is the best for the E90 NA, hence the bmw PI (too pricey but good looking; but you do get more air volume i.e. flow that is pressurized into the plenum and additional air pick up from underneath the windshield area), the dinan ram air intake (gets you more ram air from the break cooling vents up front), gruppeM (same thing as bmw PI, not sure about additional air pick up), the EURO OEM box (more air volume than the US OEM box and my favorite from all of the above in terms of cost/gains/satisfaction/fun)....and you already have scoops that take care of ram air directed entirely into your box and not your engine bay. I do share the same passion as BMW engineers "efficient dynamics", getting the ultimate in the most efficient way... Hope this helps. Now, if someone can only tell me if they have tried a BMW PI w/dinan ram air intake, I think this is the sweetest set up (it may require a tune if the engine is running to lean to balance out). |

K & N Filter replacement causing rough Idle?
Has anyone experienced any issues with the oil from the filter ruining their MAF sensor or causing rough idle start-up issues? I recently changed my air filter (78K and I figured it wouldnt hurt to replace. While I was @ it I bought a K & N replacement which I was thinking was of better quality than the stock paper.
Anyone have any input or experienced similar issues? |

Many thanks for the reply. Is this something that you had to do frequently? Did you experience a SES light? I have a service appointment tomorrow and was thinking of maybe removing the K & N replacement filter and putting the original dirty one back in (cant believe I said that) but don't want them to say that I need a replacement MAF due to the oiled filter issue. Thoughts? |

You may have already gone to your appointment, but I wouldn't worry about putting the stock filter back in. I would simply clean the MAF before you go in, or if you're under warranty ask the dealer to clean it.
