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. 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!

Not to be used with Holley LS valve covers PN 241-88 through 241-91

Fits directly into stock valve covers and fill tubes on LS2, LS3, LS7, LS9, & LSA applications (Fill tube must be used with LS1/LS6)
