Cusco’s differential cover for the Subaru Impreza WRX STi (VAB) is made from machined aluminium, and is slightly larger to hold more differential oil (up to 500cc). The fins integrated into the cover and the extra oil helps cool the differential under racing and hard driving conditions, prolonging the life of the differential. The cover has fittings ready for an oil temperature sensor and a differential oil cooler.
The following genuine Subaru parts are required for the install of the Cusco differential cover:
Air breather cap 38354AA020 × 1
Gasket (Differential Carrier) 38353AA050 × 1
O gasket 803920050 × 2 if an oil temperature sensor is installed.
Available in blue or silver.
