Vehicle-specific boost leak testers for Mustang.
Check the engine and year in the product name, or text us a photo of your setup and we'll point you to the right kit.
Boost leak testers for the Ford Mustang. The 2.3L EcoBoost kit uses a 2.375" billet aluminum end cap that mounts right on the turbo inlet flange, so you can pressurize the charge pipes, intercooler and intake manifold with the engine off. A leak there is a common cause of P0299 underboost and lost power on the EcoBoost Mustang.
For supercharged Foxbody Mustangs, there's also a tester for Vortech V-3 Si and SCi superchargers.
Remove the intake to reach the turbo or supercharger inlet, install the tester, and start around 5 PSI. Listen for hissing, then spray soapy water on the couplers and joints to find the exact spot. See our How to Boost Leak Test guide.
