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.
