APS Tumbler Delete Subaru STI 04-05

High Horsepower demands a free flowing intake system that is unencumbered by the restrictive stock Tumbler Generating Valves. The bolt on APS Tumbler Valve Delete Housing is a precision machined aluminium housing that replaces the stock Subaru component (which mounts between the cylinder head and the intake manifold/throttle body assembly) - and dramatically reduces the restriction between the throttle body and the inlet valves at high horsepower levels.

Also included in the APS Tumbler Delete system are two precision manufactured Throttle Position/Servo couplings. These components are mandatory for continued correct operation of the tumble control drive/feedback system. Without these components, the engine management system will detect a tumbler valve malfunction.
