Earl's Oil Fill Caps

Quality Billet PCV Vented Oil Filler Caps

Earl's Oil Fill Caps were designed for the addition of a catch can without significantly modifying the valve cover. These caps feature an internal battle for reducing oil transfer along with a -10 AN o-ring style port for easy connections to a catch tank or PCV. The premium billet aluminum construction utilizes an anodized finish to provide a durable and clean appearance.
