Description

The Cusco Increased Capacity Rear Differential Cover (part 692-008-AS) is a direct bolt-on replacement for the factory rear differential cover on R180-equipped 2004-2021 Subaru WRX STI models. Machined from billet aluminum and anodized in silver, it increases oil capacity from the factory 0.8-0.9L to 1.2-1.3L, with internal baffling and heat-sink fins that promote cooling under circuit and aggressive driving. Pre-tapped M16 x P1.5 ports allow an external differential oil cooler to be added later. Installation requires Subaru OEM air breather cap and gaskets (sold separately).
