I am buying a smooth air intake coupler from a website and would like to know what size to get. I know it's somewhere between 2.25 inch to 2.75 inch diameter but I'm not sure and don't want to buy the wrong size. This is for a 2006 C6 Corvette. Thanks!

Someone please help me, my car is just sitting outside waiting for this part and I don't know what size to get for the diameter of the coupler.

hey man, i know they have a thread somewhere but it would probally be faster if you took a measuring tape and measured the opening, the size of the couple given in inner diameter so measure from outside edge to outside edge of the pipe, the MAF to TB and MAF to intake are two different sizes, the website carries reducing type couplers say if one pipe is 2.25 and the other is 2.75, good luck

I don't know about the 06, but my 08 would need a 4"..The TB is inside diameter is 90mm, which is just over 3.5"..You need to go out and re-measure, because 2.5" is for a Honda or Toyota...

I really appreciate the quick responses! Thanks, 4" sounds to be right. 2.5" or so would be kinda silly for a Vette anyway. lol.
