Default coupler sizes?

What diameter silicone couplers do I need to connect my 05 MAF and OEM throttle body? I measured and think it is 3.75 but need to make very sure before I spend money. Thanks

I'd like to know this too. I see one for sale in the parts area which claims 3.75" is the correct ID.

Some of the ones for sale at Zip Corvette look like they have different ID at each end.

Some of the import turbo oriented sites have silicon ID couplers under $10 (without clamps) that would get rid of that accordion style stock piece. Even my local Kragen had some, but I don't think any were big enough.

Anyone know, for an LS3 with factory airbox what size coupler is needed? Is it a bad idea to replace? Does that accordion piece actually have some greater purpose than looking rather ugly?

Thanks!

Why don't you guys take yours off and measure it? You learn a lot more if you do something yourself rather than ask here.

That is what I did bro. 3.75=96mm OD so it seemed to be the best option
