APR Presents the MQB Platform Boost Leak Tester

August 10th, 2015

release-boost-tester-large

Boost leaks are a common cause for running issues and power loss on turbocharged vehicles. Leaks can come from scenarios as simple as a tiny hole in an intercooler or charge piping, a leaky connection, damaged DV or PCV and/or any number of other locations making troubleshooting very difficult. Furthermore, locating a leak is made more difficult due to the necessity to pressurizing the system, which typically only occurs while physically operating the vehicle. The APR Boost Leak Testing Systems allows for both visual and auditory inspection on a stationary vehicle. The kit allows for supplying and regulating a continuous supply of compressed air, typically via an air compressor, through the system. Read More
