NRW Design's latest project is the Ultimate BMW Billet Oil Cap. This cap is made of 6061 machined aluminum, with the retaining wing made from nickel plated spring steel, anodized in satin black. This oil cap is made to adjust and tighten to your valve covers by rotating the main section of the cap. Once locked into place the main section of the cap is meant to stay in position allowing access for oil via the center portion of the cap. The top section is used to seal the cap and does so with amazing style. This will allow a completely sealed mated surface of both valve cover and oil cap. Stopping leaks permanently! The added value with the cap is its ability to screw a funnel system to the cap to allow for dripless oil changes every time! The funnel system is also included with the oil cap! This is why we call this the Ultimate BMW Billet Oil Cap!
