LS Holley Stock Valve Covers Oil Cap


Model Number: 241-224

Holley’s new Oil Fill Cap for LS engines removes the oil fill tube that come stock on LS engines and replaces it with a cap that can be configured five ways plus custom option! The cap screws directly into all stock valve covers! The base is made of the same glass–filled material as the factory to ensure durability. Each cap comes with an aluminum insert that can easily be painted before assembly, and a domed Holley decal can be placed on the aluminum insert or directly onto the cap base! With paint in hand, the options are endless!
