A boost leak tester is an essential tool for any Z32 owner, with this device you can simply and effectively locate boost leaks throughout your system. Boost leaks rob your car of power, can cause drive-ability issues, and can potentially cause damage to your turbos or engine.

The boost leak tester is designed with several factors in mind. It is manufactured from high impact plastic to assure long life and features an exclusive bead rolled design to help retain the booster in place while testing. Other testers we have seen do not feature this bead roll and can pop out during testing.

A boost leak tester is very easy to use and requires only that you remove your airbox or filter along with the mass air flow meter, then insert the tester into place, tighten the clamp to secure it and pressurize the system. We recommend no more than 10 PSI be applied when testing for leaks.
