Outer Diameter or our MAF's
 

let me know if you could....OUTER DIAMETER...somebody go measure LMAO..seriously..im at work lol I just need to know...and the OD of the intake too if someone could...

I know on my Monte SS, when I replaced the stock accordion intake hose with a silicone hose, it was a 3.25" I.D. hose that was needed to go over the MAF end and throttle body... so, the OUTER diameter of the MAF and throttle body should be 3.25"...

hope that helps...

I think some 3.5s have little 1/8 spacer pieces to bring it down to 3.25.

yeah, this helps out a bunch guys...THANK YOU...trying to figure out what MAF im going to run for this turbo...lol..got the IC and pipe up and ran, but now its a reducer and coupler game for the MAF...im going the LS7 MAF route i think...so that means im going to have to come off the intake at 3.25" up to a 4.00" over the LS7 MAF and then from the LS7 MAF 4.00" down to 2.5"....i dont like that idea...i think i need to step down in pipe to...not just purely reducers LOL
