75mm MAF to 92/92 Fast
Tomorrow I am installing my FAST 92/92. The problem I have is connecting a stock size 75mm MAF to a giant 92mm Throttle body!!! what can I use to fit that mis matched 75mm maf to 92mm Throttle body?
I know what you thinking...buy a 92MM LID and larger MAF and solve my problem. Well hollidays are here and money is tight so I am currently going with the stock size LID and MAF.
what the heck can I buy to connect the stock size MAF to a FAST 92/92?
P.S. Will a Smooth bellow connect to a stock size maf and to a Fast 92 Throttle body or do I need a larger MAF for the smooth bellow and not as large Throttle body? AHHHH please help!

Have you tried using what you have now? Smooth bellows will work also. Soak it in hot water to expand it before attempting to install. I have my stock bellows streched on my 92mm FAST. it did take a lot of persuasion though.

well what I have right now is a K&N FIPK cold air to a stock size grenetelli MAF to stock throttle body. I didnt figure that hard plastic would budge from 75mm stock to fit my Fast 92/92.... but I do still have the stock lid laying around if any of that stuff will work

I got a silicone coupler like this off ebay.
Here is one that mite fit, but I dont know your mesurments that you need, so this is a 5" to 4" reducer.

The stock bellows will fit over the 92mm throttle body. Put it in a pot of hot water first - makes install easier.
