FMSP3 is the Forge Motorsport Blow off adaptor for the Alfa Giulia/Stelvio & Jeep Wrangler 2.0T. The spacer is a pressure release system that has been designed by our CAD team and utilises a well proven design which is tried and tested. It is used with the OEM diverter valve to vent extra boost air into the atmosphere instead of sending it back into the engine's intake piping, which helps with turbo longevity.
