Apexi Blow Off Valves

Apexi Twin Chamber Blow off Valve is always available at OptionImports.com. It utilizes a revolutionary new Dual Chamber design engineered for high and low boost response. On turbocharged vehicles, Apexi BOV release excessive boost pressure trapped inside the intake pipe when the throttle is released. This release of pressure is important because as the vehicle accelerates, the turbo builds a high pressure air stream through the throttle body and into the motor. When the driver lets off of the accelerator and closes the throttle plate, the trapped air instantaneously has nowhere to go. This trapped air begins to travel back towards the turbine blade causing excessive strain on the blades. Prolonged exposure to these conditions can cause premature turbine wear and eventually cause turbine failure. The A’pexi Twin Chamber Blow Off is designed to effectively release this pressure into the atmosphere. The unique twin chamber design allows quick response without causing any excessive turbo lag between gears.

The unit features 3 point sound adjustment and a spring tension adjusting screw. The piston sits inside top chamber for reduced wear and a valve sits in bottom chamber using the assisting vacuum hose to release excess pressure. The valve is capable of up to 2 kg/cm2 (29.4 PSI) of boost and is housed in a high finish aluminum housing. From street to race applications, it is no wonder why the A’pexi Twin Chamber BOV can be seen in many of today's high power performance vehicles.
