4.00" Boost Leak Tester Kit

🔧 Universal Boost Leak Tester Kit – Billet Plug, Silicone Coupler & T-Bolt Clamps | Turbo Inlet Pressure Test Tool

Eliminate hidden performance loss and increase power by tracking down boost leaks the right way. Our Universal Boost Leak Tester Kit is the most effective way to pressurize the entire intake system and identify any leaks quickly and accurately.

This simple yet powerful tool connects directly to any turbocharger inlet and features a ¼″ NPT tapped port to attach regulated shop air (maximum 30 PSI) using your preferred air fitting. Once pressurized, spray suspected areas with a soap-and-water solution to instantly detect leaks.

Fixing boost leaks not only improves turbo spool and power delivery, but also results in cleaner exhaust and better overall drivability.
