This is a Brand New OEM Subaru Hydraulic Timing Belt Tensioner.  It will fit most all EJ series engines, including the 2002+ WRX, 2004+ STI, 2005+ Legacy GT, and 2004+ Forester XT.

These can be re-used, however you have to be extremely careful when you are compressing the piston to replace the pin.  If this tensioner should fail, it can result in engine damage, which is why we strongly recommend that our customers install a new one when replacing their timing belt.

The Subaru Part # for this part is 13033AA042
