Somewhat crude. Very vintage looking. Super rad. This outer primary Inspection Cover / Primary Plug / whatever the fuck you want to call it is polished to a high shine for you chrome heads out there (2nd Photo).
Feeling more Filthy than that? 20 seconds with a Red Scotchbrite Pad, and your existing hardware, and you've got the dull finish that matches your outer primary (1st photo).
Includes stainless mounting hardware and o-rings.
