I did the search first...

But anyone know what the measurement is for the I.D. of a rubber hose to fit over a TPIS 90mm throttle body. I'm sitting on the intakehoses.com site and i just completely forgot what i needed.

3.5" I.D. hose or 4" I.D. hose? custom setup so no worries on the MAF or lid

nevermind... for future reference, it is 4.25" for the O.D. of the TB lip
