TurboSmart has been building the world's best blow-off valves for 25 years. The Kompact Shortie Dual Port for the N55 is a direct replacement for the OEM diverter valve, venting partially to atmosphere (the psssh) while recirculating the remainder for clean idle. No check engine light. Responds precisely at low boost, holds everything the turbo can make at the top. Proven on N55 builds at 30+ PSI.
