The AFE looks very similiar to the EURO box I bought. The EURO box is more completely sealed. I did a flow test on the EURO box and with and without the snorkel and front elbows in place, it flowed the same, no difference. With and without the K+N filter (Cone shape on the EURO) it flowed the same so the K+N caused no restriction or minimal to even detect. With and without the lid it flowed the same. When I take off the stock air box I will flow it to compare. Interesting when I blew air into the snorkel to simulate 'ram air/scoops' the flow did increase. When I flow the stock box I will post all the numbers.

How did you do your flow test? Can you also measure temp?

Just to clarify, an aFe intake can be installed on a 328xi without any modifications to the housing of the air filter. I have an 2007 e90 328xi non-lci and just installed an aFe intake (pro dry-s) this past weekend. The only modification I had to make was to slice off a small plastic nib where the housing clamps to the engine (easy cut with an exacto knife, it's smaller than the size of a tic-tac). Some have mentioned that there can be a bar in the way, or that modification to the housing is necessary. Just wanted to clarify that this is not the case with all xi models. Not only does it sound great, but I've noticed an improvement in acceleration (combined with aftermarket exhaust) between 2000-4000 rpms.

Can you post some pics of your setup. Where did you purchase it and how much did it cost?

No I have not had any problems with not having the Carbon Filter and the dealership works on my car and no issues.

Meaning those stock air scoops are large enough, the limiting factor is the size of the stock intake duct and the paper filter.

Over all if money is not an issue, and performance, not the sound is what you are after, the BMW performance intake is the way to go.
I agree the aftermarket scoops might not do much but at high speed it helps push alittle more air into the intake box. And they only cost $50 or $60 so it's no big deal. Plus if you are under warranty the BMW performance intake will not cause you any problems.

Where did you get them for only $50 or $60?

Also how did you remove those two damn plastic pins holding down the air snorkels?

Here are some pics, sorry about the quality, it dark in my garage. It is a standard setup, no extra modifications. I also have scoops installed. To take out the pin, use a pair of plies and pull the pin straight up. To remove the grommet, just take a flathead and wedge it underneath and pry it out, working your way around the grommet. If you break it, don't worry, a replacement only cost like 30 cents from Tischer.

To make your life easier when your installing the scoops by yourself, take out your grill by pressing the clips in the inside and popping it out. Then use a piece of tape on each side to hold it up in place, place the take on the outsides lip (closest to the wheels). It's easier if you have two people, but can be done by one person.

I forgot to mention that I got it from Turner Motorsport, ran about $330. Their service was fantastic, would definitely order from them again. I thought this was a little pricy, and then looked into the Dinan and BMW Performance set-ups and those were a lot more than I thought was worth spending on it. The exact model I got was "aFe Stage 2 ProDry S Intake Kit"

No one has gotten a CEL because of the afe? Installed mine and 2 days later my CEL came on. It was the air ratio that was off.

I just finished installing it, very nice, took about 20 min to get it in. No mods at all. I'll post pic a bit later. Sounds great.

I pulled the trigger on the aFe Stage 2 Oiled version. Ever since I replaced my factory tube to cut out the stupid silencer I've been meaning to come up with a permanent solution to the mess of piping going to the stock intake. It's currently being packaged and will be ready to ship out tomorrow thanks to one of the members on this board no longer needing it (Wifey doesn't like vroom vroom I guess).

Despite the tit for tat BS that everyone has been shooting back and forth about the aFe, I found several posts made by the same guy who happens to be putting in a lot of effort to get us our first realistic and reliable forced induction setup saying it was worth the money. Thanks Gavin for convincing me. It'll go nicely with my upcoming plans this summer.

afe oiled?

so alpine, you recommend the afe oiled?
they seem to be the most cost effective intakes, right?

i'm looking for a throaty masserati sound, and maybe a little increase in hp, and NOT for $1200 like my local dealer is recommending. i would even consider a negligible hp gain/loss if it meant a good sound & not one of my limbs.

feel free to direct me to the correct forum if i'm out of place here.
thanks.

The aFe is probably the best all rounder and its even better if you can find it second hand in good shape. Then again, at $400, its a bargain compared to the stealership. I dunno about maserati sound but you will love the sound it produces. Guaranteed.
