Get your boost back and get Full Performance From Your Turbo!  

This boost leak tester end cap is designed to fit inside of a flexible rubber or silicone hose and allows you to pressurize the charge system with compressed air while the vehicle is off. 

This is an important tool every turbo car owner needs in their arsenal of tools.  It will keep the turbo healthy by eliminating leaks in the boost path and not allowing it to overspeed compensating for a boost leak.  This will eventually lead to bearing wear and shaft play. Boost leak testing is a must if you are tuned or any time you are replacing any components in the intake tract such as charge hoses, intercooler, manifold, vac lines, injectors, etc.  Also a must if you are going to the track and want the peace of mind that the turbo won't over-work or risk blowing any hoses off that are loose!
