This is the factory lower hose assembly for the stock evap system; it lives under the intake manifold and connects to the evap system purge valve, among other things. We find these hoses often crack and leak, leading to Check Engine lights. Replace the tired hoses with some OEM Subaru fresh ones for years of trouble-free operation.
Hose assembly comes pre-assembled with tee, braided shield, and three hose segments.
Fits all GD-chassis WRX and STI, 2002-2007.
