Air intake coupler size?
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!

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
