I don't want to badmouth a product that I have not used, but there were a lot of problems with the Vararam intake when it came out. First it took them forever to get them out, I gave up my spot in line and went to the CAI. When they did come out people were reporting issues with bucking and surging at idle and low rpms. There were issues with build quality of the intake. They would not agree to have thier intake tested along with others. That being said , there are some people who swear they are the best intake out there.Vararam also seems to have good customer service with all the problems they have had. There must be some minor difference in the '12's, that they had to make a newer model intake.
