The Oil Control Valve (OCV) is responsible for metering oil to the AVCS system that moves the intake cams around on 2015+ STI's. We've seen some weird problems caused by failed or failing oil control valves. Sold individually.
Note that this is the oil control valve for the INTAKE cam. There is a separate OCV for exhaust cam.
Fits all 2015+ Subaru WRX STI.
