Prova Hi-Press Bypass Valve
This bypass valve features a higher spring rate than the OEM part and is constructed to be extremely durable. With a valve opening pressure approximately 20％ greater than stock, turbo response is improved while preventing the problems associated with using an atmospheric blow off valve on a mass airflow sensor equipped vehicle. The black alumite finish makes it an excellent dress-up part for the engine bay as well.
