The Ultimate BMW Billet Oil Cap

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!  Our latest V2 cap as shown also has the ability to add a 10 ORB/AN fitting for those looking to add a breather or catch can setup to your S65 engine. The ORB/AN fitting is not included but can be added at purchase at a discounted price. This is why we call this the Ultimate BMW Billet Oil Cap!
