After a countless number of requests, the K-Tuned Billet Oil Cap is now available. For a design, we weren’t trying to reinvent the wheel here, so we kept things very simple. Starting with 6061 billet aluminum blank, we threaded the bottom, machined a groove for an o-ring seal, cut out the center and placed 7 moon cuts around the outer circumference for grip when loosening or tightening. The cap is then fully polished and finished in your choice of 5 anodized colors: black, silver, red, blue, and gold.
