Complete with box, elbow, snorkel and shorter throttle body intake tube. Fits E28, (intake tube for B35 only), helps if you don't have a fuelcooler. Need to supply your own filter. $50 shipped.
Edit: I got a few PMs about this and some people seemed confused about fitment. This airbox comes with a short intake tube that does not have the port for the vacuum purge valve which is required on a typical B34. If you have a B35, use this tube, if you have a B34 you have to shorten your intake tube, likely by cutting off the bellows part. The middle pic shows the difference in length of the B35 intake tube with a stock B34 airbox. That's how much you'll have to shorten your tube for the B35 elbow to line up.

Larry, I didn't have any trouble with the mount, and was able to close the hood without any drama but it was riding against the fuel cooler. I thought this might cause chaffing problems later on (much like Matt's new g/f ) so I decided go back to stock for the time being. If I can ever get around to removing the fuel cooler I'll give it another go.

Fuel cooler - hey now, that sounds like hot rod stuff! I don't have one anyway. I have not tried the b35 air box on my 535 E28. It's the E23 735 the b35 air cleaner will not fit into. Looks like a sawzall will be needed to remove the mounting for the orig air cleaner. The sawzall however, is probably not a good idea for resolving any chaffing problems Matt may encounter with the new GF.

I can't answer that question accurately as I've never tried. I suspect it won't, since the factory box for that car was the same as the E28. The advantage of using this box seems to be a better looking engine bay and perhaps increased surface area across the filter membrane. Without additional mods to the motor I can't see the latter part doing much. At the risk of superfluous technical discourse, I don't really understand why the factory would increase the intake capacity on the B35 with increased manifold and port size, yet retain the same throttle body. I assume the airbox is also higher capacity but again, the TB would be perceived as a possible constriction, unless it was simply over-sized for the B34 to begin with. Or maybe the higher velocity through the same opening was the win. I dunno, out of my wheelhouse.

I figure it is the same as all the plastic shit covering BMW engines for the past 20 years since form-follows-function seems to have been reversed. I like it because the stock box covers my polished valve cover.
That's what your new girlfriend said to me!
