The Power Driven 4" Boost Leak Tester is the ultimate solution for efficiently and comprehensively detecting boost leaks in your diesel engine. Designed to provide a hassle-free experience, this innovative tool allows you to pressurize the entire intake tract, enabling quick and thorough leak detection like never before.

Our 4" Boost Leak Tester attaches to any 4" turbocharger inlet* and features a 1/4" quick-coupler to allow the user to connect regulated shop air (30 psi maximum). Once you have the intake pressurized, all you have to do is listen for leaks and spray suspect connections with a soap-sud solution to find them. After isolating and correcting all boost leaks, you will find increased turbocharger response, cleaner exhaust, and more power!
