The Dura-Lite™ intercooler Tester-Kit™ is used to check for boost leaks or pressure issues within an intercooler system. Here's how it works and how you can use one:

Seals the System: The Tester-Kit includes plugs/ caps that fit inside the inlet and outlet of the intercooler pipes to seal them off from the rest of the system.

Pressurizes the System: A compressed air source (like an air compressor) is connected to one of the plugs, which has a Schrader fill valve to pressurize the system.

Detects Leaks: By adding air pressure to the system, you can monitor for pressure drops, listen for hissing sounds, and/or use a soap-water solution to identify the specific location of a leak.
