Get rid of the dull yellow plastic under your Subaru’s hood and upgrade your engine bay with the IAG Revolve Engine Oil Fill Cap. This sleek black aluminum cap combines functionality and style, offering a dependable seal against the oil filler neck while adding a refined, custom look.

Designed for versatility, this Oil Fill Cap features a removable plug that can be replaced with an optional -10AN fitting. This allows you to run breather lines to a catch can such as IAG's drag catch can, making it an ideal choice for those looking to improve crankcase ventilation or integrate a drain-back feature into a custom setup.

Made from precision-machined 6061 billet aluminum, our caps offer superior strength and durability. It features a sleek black anodized finish, providing enhanced corrosion resistance and a high-end appearance.

At the center of the IAG Revolve Engine Oil Fill Cap is a sleek anodized aluminum insert, which is laser-etched to reveal a universal oil symbol, but can be flipped to show the solid color. The inserts are easy to swap in seconds, thanks to the accessible design inside the cap—just use a small tool to pop the insert out and choose your preferred side.
