We now have 4 inch boost leak testers for you guys with big turbos!

This listing is for 4 inch MPx boost leak tester, which is for use with BIG AFTERMARKET Turbos. This will NOT WORK WITH THE FACTORY TURBO. If you have a Factory turbo, see our listing for a 2.5 inch inlet boost leak tester.

Have you ever experienced any of these situations with your turbocharged car?

# Had less peak boost than you had a few months ago ?
# Does your car seem a little bit slower ?
# Ever wonder if you could have a leaking pressure pipe in your engine?

If you’ve answered yes to any of the above questions, then this device could come in very handy.

This device is a piece of test equipment that will allow you to find out if there are any leaks from any hoses, clamps, cracked hosings that could be leaking boost.

The boost leak tester is a very simple piece to use, you simply remove the intake tubing to the turbo, and then clamp on the boost leak tester onto the turbo inlet. Then pressurize the turbo and piping with a air compressor. This will fill the piping with compressed air and will allow you to listen for any leaks.
