All the other X's have a different stock intake. For some reason the 4.6 has two additional units that runs to and from the stock intake. One is an air pump, a pipe runs into the top half of the box and sucks in filtered air. The other is some type of actuater gate that I think opens and closes under acceleration.
Take a look here of a pic broknlgs24 provided

This is the small actuater gate


This is the pipe the leads from the air pump to the top section of the stock 4.6 intake

I'm gonna try a different route with my intake...and if i fail...i'll just get the AFE.

Anyone know how much room we have: from the HFM to the edge of the fender? The intake i'm looking at is approx 8-9 inches long...and was worried it wont fit. I assume the inlet diameter is 3.5inches?

sorry for asking this, dont have my x5 yet...its on the transporter now on the way...

thanks

I have a K&N mini filter that looks like this:


Not sure the exact size but it fits perfect on the air pump hose. You can view more here. http://www.knfilters.com/vent.htm

sooo how do you guys like the AFE? Any problems? Does anyone have a reliable dyno plot showing any gains? What about the Gruppe M intake...anyone know how much it costs or has a link?

The Gruppe M intake is like 1200 bucks. You'll feel better donating that money to charity, as compared to giving it to Gruppe M.

why not just custom make an intake? Filter, mounting hardware, pipe, clamps, mini filter. cover.???

I installed my AFE intake in May and noticed a smoother throttle, and felt like more power. MPG down because I drive it a little harder now. I am in the 3,000 mile per year club. My job doesn't allow me to drive it dailey. It would be hard to sell projects/improvements to people when I pull up in a BMW and they drive chevys and toyota's. So on the weekends I tend to have a heavy foot.

Has any one installed a high flow throttle body with AFE intake? last question has any one installed Eisenmann racing exhaust on there 4.4?

Do you have nay pictures of your setup? Anyone do this with a 3.0i?

Hmm... after watching some vids and hearing the sound of the AFE, im regretting ordering a K&N airbox filter :P

Ah well, maybe I'll do it after I've done the high-priority maintenance.
