Oil Cap
Great quality, and it is the same clip style of stock, rather than a solid piece that won't ratchet.

RIFFRAFF DIESEL BILLET OIL FILL CAP 1994-2010
I recently purchased this cap in RED on my last order to match everything else I've bought here and the picture here on website doesn't do it justice. It looks great sitting on my freshly painted V/C's in VHT Gloss Black. Getcha one, you won't be disappointed. Thanks Riffraff !

Oil fix cap
I ordered the red one & it looks just like the picture! I love it! L99 F250 super duty!
It seems a bit $ but the quality & style is amazing. If I had a 2nd 7.3 I’d buy another! -
