Products - Boost Leak Testers

90-96 Nissan 300zx Turbo and Non-Turbo
The Boost Leak Tester is a must have tool for any z32 owner. With the strenuous amount of intake piping the z32's are prone to leaks. With this tool you can eliminate all of your vacuum and boost leaks giving you the best idle, best throttle response, solid boost, and best performance. When choosing the right tester for your application start with the type of intake you have. Single Pop or Dual Pop intake (refer to pictures below). You can chose between a tire valve adapter or a male air compressor coupler. You also have the choice of having a gauge built into the tester. The gauge isn't needed, but is quite useful for showing the manifold pressure and making it easy to see if your intake system is holding pressure. The gauge is also useful in making sure you do not exceed the maximum amount of pressure you apply while leak testing, which could damage your engine. The gauge is shatter-proof with a very easy to read display. To see how the tester works or what tools you'll need to operate the tester, please refer to the Guides section. Any questions please Contact us.
