Say goodbye to the plastic oil cap on your GR Corolla. The FHS Oil Cap features a six-sided design that provides both grip for removal and updated styling. It is available in three distinct colors that add a pop of style to your boring engine bay. The oil caps are machined, anodized, and laser engraved in the USA by Verus Engineering. The oil cap is easily installed by removing the old cap and threading the new one in its place.
