The valve of the American company TurboSmart is an excellent proposition for those who want a valve more efficient than OEM.
Kompact valves are designed as a direct replacement for OEM valves.
They are characterized by faster operation, better flow and higher rechargeability.
The valve returns part of the pressure back to the intake system, and the part releases to obtain a characteristic sound effect.
