Ok, I tried search but came up with all kinda of stuff that wasn't even close.

Easy question. I'm switching to a 90mm throttle body on my 99 Formula. Do I need a special bellow to attach to the MAF or will the stock one work?

yeah the stock one won't work, you are gonna need something thats goes from a ~3" to a 4", check ebay or napa, or maybe even home depot for a silicone coupler

If you are using one of my throttle bodies, the stock one will work. The SLP one fits it nice though.

I was wondering this as well...I think I'm gonna check lowes/home depot for something that would work well.

Mine is actually the FAST 90 TB...so, basically if the stocker doesn't work I need a 3-4 silicone coupler/reducer?

with a 2nd set of hands to help, and a little silicon lube....i was able to get my stock acordian coupler on to my FAST 90mm TB last month.

+1, I just got my NW 90 the other day, brand new via SDPC. The thing is a work of art.

I used the stock bellow with my FAST 90mm throttle body. Just needed to be heated up a bit with a torch and she slid right on. I even reused it when I put the 90mm TNT ring on it

I bought a coupler from Lowes for $6.00 that worked fine. 4x4 for me as I have an 85mm MAF.
