Product Description

The Cusco 672 009 AN is a vehicle-specific oil catch tank engineered as a direct-fit upgrade for the 2002-2005 Subaru Impreza WRX and WRX STI (GDB Applied C-E). On turbocharged EJ-series engines, crankcase blow-by gases carry oil vapor and unburned fuel residue through the PCV system and back into the intake tract - degrading fuel quality, coating intake valves, and potentially causing detonation under high-boost conditions. The 672 009 AN intercepts this blow-by inline with the PCV system, capturing contaminants in its 0.3L polished aluminum canister before they can reach the intake or intercooler piping.

Designed as a vehicle-specific solution for the GDB chassis, it installs directly using factory mounting locations with all brackets, hose, and hardware included - no fabrication or modification needed. The mirror-polished body, blue anodized fittings, and powder-coated Cusco blue brackets deliver a clean, purposeful engine bay appearance that matches the performance intent. A straightforward and functional upgrade for any WRX or STI owner looking to protect their engine and maintain combustion efficiency.
