One of the easiest ways to lose power is to have a simple leak in your intercooler plumbing. The STM boost leak tester is the best tool to help find and repair these leaks. 

This kit includes our 3" billet aluminum core, two T-bolt clamps and a standard size valve stem.  The valve stem will be shipped with the Schrader valve removed so you can discharge air as fast as possible when needed.  The kit also comes with a 4-Ply Silicone coupler to adapt to the size needed for you application
