BMW Billet Aluminum Oil Cap

BMW Billet Aluminum Oil Cap Say goodbye to leaky oil caps and weak OEM designs. The EAE Motorsport Billet Oil Cap is engineered for high-performance BMWs that deserve better. This cap replaces the failure-prone factory unit with a CNC-machined 6061-T6 billet aluminum body, a thicker high-temp gasket, and a reinforced dowel pin locking system that never bends or loosens. BMW’s factory cap uses thin stamped metal locking tabs that lose tension over time, especially under heat and vibration. The result? A cap that no longer seals tightly and slowly leaks oil onto your valve cover. We fixed that — permanently. The EAE cap locks in tight and stays sealed, mile after mile. It’s the upgrade your engine bay needs, combining performance, reliability, and a clean motorsport look.
