Important Note Regarding Oils, Additives, Aerosols & Liquids

This listing may contain a product with transport restrictions. Items containing oils, additives, aerosols, adhesive or other liquid/chemical-based products may be subject to shipping restrictions depending on their current warehouse location, carrier requirements, and applicable transport regulations.

Some liquid and aerosol products are restricted for air freight or certain road freight routes and may require alternative transport methods or dispatch from a specific warehouse. While the majority of these items ship without issue, these factors can occasionally affect available shipping options or delivery timeframes.

If you are working to a tight deadline, require urgent delivery, or are unsure whether a product can be shipped to your location, we recommend contacting the StreetFX team prior to placing your order so we can confirm availability and the most suitable freight option.

Reference Information

Oil Fill Cap, Vented, Screw-In, Plain, Round, Black Anodized, Billet Aluminum, LS, Each

Earl's Performance vented oil fill caps eliminate the need to modify your valve covers when adding a catch tank to your racing engine. These caps are required by most sanctioning bodies in racing applications. Choose from two versions—one that fits OEM valve covers (GM LS, GM Gen-V LT, and Ford Coyote); or the version designed to fit Holley cast aluminum GM LS valve covers. These billet aluminum vented oil fill caps feature a black anodized finish. Order the vented oil fill cap that best suits your application.

Additional features and specs:
• Internal baffle inside cap to help reduce transfer of oil to catch tank
• Screws into valve cover like ordinary oil fill cap
• -10 ORB (7/8 in.-14 straight thread) O-ring boss port for use with AN hose to catch tank or PCV
• Use with O-ring port hose end AT849010ERL; or O-ring adapter AT985010ERL (straight) or AT949010ERL (90 degree)
