Z1 Motorsports Boost Leak Tester

starstarstarstarstar 5/5 - (7 Reviews)
Fits models: 300ZX / 350Z / 370Z / 2000-2003 Maxima / 2009...

Product Description

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. 

Z1 Motorsports 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 Z1 Motorsports 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. Z1 recommends no more than 10 PSI be applied when testing for leaks.

Size is 82.177 millimeters = 3.235 inches around bead roll 

This product is sold with or without a pressure gauge as an option below.

Included is one (1) boost leak tester. Models with dual intakes will need to source a plug for the second intake (PVC pipe plugs work great!) or a second tester without gauge can be used.

Questions our customers have asked

I'm converting from single pop to dual-pop, so I already have a single boost leak tester. Would you sell one side of this with the valve only?
The standard price boost leak tester without gauge comes with just the valve installed.
Would this work on the momentum turbo kit?
Sure will Max!
