OEM Washer (M10), Turbo Exhaust: DSM/EVO

Genuine OEM part.

These washers are used with the bolts and studs that fasten the turbo's exhaust housing to the exhaust manifold.  

A pair of these special washers is used for each bolt/stud. These washers are special concave-shaped and are designed to be used in pairs and positioned under the bolt head in opposite orientations such that their resulting shape resembles a football. (There are two dimples on one side of each washer.  The sides without the dimples (which is the concave side) are meant to face each other, and thus each side with the dimples will face outward and be visible). This positioning acts as a spring to keep pressure on the underside of the bolt head to prevent it from working itself loose.
