Here is what I did:For you guys running the gt350 cold air intake with stock throttle body... where can I get the gasket to put on the throttle body so it can fit properly? Or part number? Thanks
A stock GT throttle body is 80mm. A GT350 TB is 87mm. That's an increase of 3.5mm of radius length center to circumference edge.
In other words you need to build up the lip of the stock throttle body by 3.5mm. This is cheap and easy to do.
1. Remove the intake tube from the throttle body and measure the flange edge width.
2. Then buy a roll of Gorilla tape and cut a long, continuous strip of the tape in the same edge-to-edge width as the measurement taken from the stock TB.
3. Roll the tape around the outside lip of the TB until it reaches a thickness of about 3mm.
4. Secure the intake tube to the tape-enhanced TB.
**If you don't like the idea of using the Gorilla tape, then go to your hardware store and find a sheet of rubber of some kind that is approx. 3mm thick. Cut a strip of it with the same width and circumference (80mm x 3.14) as the outside lip of the TB, wrap it around the TB until the ends meet, secure the ends with a small piece of tape, and viola, you have just created your own rubber gasket!!
