About this product

Part #: 241-224

Holleys 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! Our 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!
