Default Throttle Body outside diameter

Hey guys just like the subject says how big around it the outside diameter of a stock 2001 LS1 throttle body??

I need to get a 90° bent rubber tube to go to my filter on my LS1 RX7 project car.

Thanks
Mike

I know you can use a 3", cuz I use a 3" x 3" Fernco, yeah it fits nice and snug the first time after that it is just snug!

Really I measured mine and it was 4". Then the MAF sensor fitting was 3.5"

Am I wrong??? 3" would be a lot easier to find stuff for it.

I measured the one on my desk and it was 3.75 or so. I'd get something in the 3.5" range so you can stretch it to fit.

Well, I didnt say I measured it with rule or tape, but I KNOW A 3" x 3" Fernco WILL FIT nice and snug! Seeings how Fernco are not sold (not even sure if they are made in 1/2" increments) here except full inch sizes, and I do not need any clamps for mine, it must be 3" straight. Stretched? YEP.
