Need to Extend the Intake Elbow

I bought a Moroso Cold Air Intake for a 94-97 LT1 and my car is a 93, therefor it is about 4" short (I don't have a MAF). I was thinking of keeping 4" of the Stock Air tubing connected to the elbow and connecting the Cold Air Intake to that. But what would be the best way to connect the tubes and keep them air tight?

I think someone recommended a silicone sleeve, but I wouldn't have a clue on where to find one of those.



Edit - Got it.


Had to put a small piece of PVC on the left inside the rubber joint. Seems like it will work perfect.

could just get a 3" diameter 4" long tube and get some connectors for it. I'm thinking home depot or something here.

You can find one at Home Depot or just about any place that carries plumbing pipe.

Go to Lowes and get a piece of septic piping or a coupler. It is already black in color and made from ABS plastic which has a higher heat threshold than PVC. You can also pick up a Fernco rubber coupler for the extra connector.
