IAG REVOLVE ENGINE BAY DRESS-UP CAP KIT FOR 15-21 STI - INCLUDES OIL, BRAKE, POWER STEERING, COOLANT & WASHER CAPS TRANSFORM YOUR ENGINE BAY
Get rid of the dull yellow plastic under your Subaru’s hood and upgrade your engine bay with the IAG Revolve Engine Bay Dress-Up Cap Kit. Compatible with 2015-2021 STI Subaru models, these sleek anodized caps replace your factory oil, brake, power steering, coolant and washer caps with a more refined look—while maintaining a reliable, factory-quality seal.
BETTER THAN OEM
All of the caps in the IAG Revolve Engine Bay Dress-Up Kit are precision-machined from 6061 billet aluminum for exceptional strength and heat resistance. Designed to outperform the factory plastic caps, each one is built to handle the harsh conditions under the hood. They feature a sleek anodized finish, providing enhanced corrosion resistance and a high-end appearance.
CUSTOMIZE YOUR CAPS
At the center of each cap is a sleek anodized aluminum insert, available in your choice of silver, red, blue, black, gold, or purple. Each insert is laser-etched with the appropriate universal symbol for each fluid system—oil, brake, clutch, washer and coolant, but can be flipped to show the solid color. The inserts are easy to swap in seconds, thanks to the accessible design inside each cap—just use a small tool to pop the insert out and choose your preferred side.
THE IAG REVOLVE OIL FILL CAP
Designed for versatility, the IAG Revolve Engine 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 our 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.
THE IAG REVOLVE BRAKE FLUID RESERVOIR CAP
The IAG Revolve Brake Fluid Reservoir Cap is a solid upgrade from the Subaru factory yellow plastic cap. Designed to withstand the heat of the engine bay, it resists the cracking and wear that can affect OEM caps over time. That means more dependable performance where it counts—by sealing out air and moisture and keeping fluid where it belongs.
THE IAG REVOLVE POWER STEERING FLUID RESERVOIR CAP
By combining Subaru’s proven venting system with IAG’s precision-machined aluminum surround, the IAG Power Steering Reservoir Cap creates a stronger, more durable solution than the OEM cap alone. Precision CNC-machined from billet aluminum at our Westminster, Maryland facility, this cap retains factory functionality while providing an extra layer of reinforcement to the original factory part. Its corrosion-resistant black anodized finish adds both protection and a custom aesthetic to your engine bay.
THE IAG REVOLVE COOLANT CAP
Like the rest of the IAG Revolve lineup, the Coolant Cap features durable billet aluminum construction and a clean, refined look. It’s a direct fit for the factory reservoir and provides a secure seal to help maintain pressure, prevent leaks, and support consistent coolant circulation.
THE IAG REVOLVE WASHER CAP
The IAG Revolve Washer Cap is built to the same high standards as the rest of the Revolve series. It’s a direct replacement for the factory Subaru cap, offering a cleaner look, improved durability, and a reliable seal that keeps fluid in and debris out.
