Hey guys, could someone help me out quick? I need to know the inside & outside diameters of the circular plastic outlet from the air filter housing (that goes to the AFM, circled in red). I don't need the outside diameter to include the little rib, just the main part of it. If you have an extra air box laying around & a pair of calipers, I'd appreciate the help. I eBay'ed an M30 air box, but it is going to take a week to get it.

I have a fully built M42 on its way, and a custom MAF conversion that I'll be seeing if I can cram an M30 air box under the hood for! I need the outlet dims so I can start working out the intake tube / velocity stack design.

Thanks!



Surely you guys are like us E30 folks & have random extra air boxes sitting in your garages collecting dust. :shifty
