There seems to be a few different kinds. Which one is used for the LS3? Im ready to order one right now but want to get it right. Also I want to get rid of the stock coupler and replace it with one from extreme psi, What size? Help would be appreciated.

 

The VR-SC1 is for the LS2 and the VR-SC1R is for the LS3 and LS7.

 

Awesome! Thank you. Thats exactly what I needed to know. Has anyone ran into problems with the new MAF making the check engine light come on?

 

I have the VR-SC1R on my 09 Corvette and have had no lights or codes on my car. This is a very good CAI system.
