Fast TB 4 1/4" OD Which means a 4" bellow won't work. The car in question is speed density, and has a Fast Toys lid with a 4" opening. So I need to go from 4 1/4" down to 4" to the lid. Any ideas how that is suppose to happen? Yes I did a search with no good information. I also checked Fernco's site.
Thanks.
Thanks.

I use this coupling - A 4" silicone charge air cooler hose works great. Has good flexability and easy to trim to allow a better fit.
Check your local semi-truck repair shop they usually have these in stock.
I just went and checks and it fits over the Fast big mouth 92mm TB.
