Default Intake duct between TB and MAF ?

My intake air duct is ripped that goes between the MAF and the TB, on my 01' Z28

Is there one that would fit my 90mm TB better? The stock boot had to be stretched allot to get it to fit over the 90mm Fast TB.

The GM # for the stock replacement is 25170358 but it would take a week to get it from the dealer.

TIA, Zach

4" to 3.5" is roughly what you need, with a 15* to 20* bend angle if possible.
FYI, measure to make sure since not all TB's have the same O.D..
