Vehicle-specific boost leak testers for Porsche.
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.
These are twin turbo testers for the Porsche 996, 997 and 991 Turbo. The 996 and 997 testers work with stock and upgraded turbos, and the 991 kit uses twin 2.5" testers. Every tester is billet aluminum with a liquid-filled gauge. Testing both turbos at once matters on these cars: a leak on one bank can hide behind normal boost on the other and show up only as uneven boost, a lean code or a slight loss of power. The intercooler couplers, the diverter valves and the throttle body connection are the usual leak points, especially on older cars where rubber has hardened. Fit both testers, start at 5 PSI and work up slowly toward your normal boost while you listen and spray soapy water on every joint. Text us if you're not sure which generation you have.
