About this product

Part #: 241-225

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!

more horsepower

What made you choose this particular product?
I had a Holley carb on the truck and wanted to stick with the brand since it was still working great. I just wanted to have the peace of mind that comes with EFI.
What were you trying to accomplish by adding this product?
Better MPG and Horsepower.
Was it easy install? Any installation tips that will help others?
It was easy to install. I took the truck to an exhaust shop to weld in the O2 bung but did everything else myself. The wiring and fuel return line were a lot easier than I was expecting.
Once you’ve had a chance to use the product, did it meet your expectations?
It exceeded my expectations.
Any additional comments?
I highly recommend this product to anyone wanting to keep a traditional look but have the benefits of EFI.
