R180 Rear Differential cover

MSISUB03-00-010

Impreza WRX & STI GC8

This a direct replacement part for the OEM R180 differential cover, CNC Machined from aircraft grade T6-6061 Aluminum, AN-08 adapters can be installed for external oil coolers and pumps as well as industry standard 1/8-NPT temperature sensor housing.

The factory STI m16 temperature sensor fits as well. The cover’s seal is insured with a Viton O-ring cord installed in a 1/16” groove machined into the sealing surface so silicon sealant is not needed. The Factory breather cap is transferable to the new cover. An additional 20% oil capacity is added without increasing weight, all covers ship in a clear anodize finish with plugs and o-rings included.
