Audi A6 & Allroad 2.7T


Product Description

Boost Leak Tester for your A6's & All-Road's 2.7T y-pipe inlet. Comes standard with a cap for your crank case vent, 30 psi gauge, tire valve stem fitting and one stainless steel T-Bolt clamp.

Fit this over your Y-pipe, and clamp it down.  The vinyl cap is used to cap the crankcase ventillation flange off the y-pipe to inhibit the test pressure from escaping through the crank case ventillation valve and into the crankcase.  Use the provided zip tie to secure it.
