I was wondering if the Joe Z intake uses TWO regular 3''x3'' couplers that you can buy at any auto shop (like Pepboys). I bought a F-Sport Intake pipe (Just the pipe) and noticed in a few pictures that the F-Sport had two different couplers. The coupler that connects the top of the pipe to the throttle body looks like a regular 3''x3'' but the one that connects to the actual air box looks like it is different as it is much rounder in the middle. I know both the pipes, Joe Z and F-Sport, are similar in design so I was just wondering if I can buy 2 of the same exact 3''x3'' to install my F-Sport Intake pipe instead of buying the "F-Sport Hardware Kit"

the joe z uses 2 regular ones. i don't know what the bulge ones does. normal ones perform just the same.

just save the money and buy 2 regular ones. if you're really worried. bring your pipe into the store and test fit it.
