Description

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)
