Billetworkz Engine Bay Caps Zero Series for 2015-2021 Subaru STI with Fluid Engraving

These caps are factory - replacement parts, not just covers. They're CNC - machined from 6061 aluminum and anodized, offering a durable and vivid finish. For 2015 and later Subaru STI models, the set includes an oil cap, wiper fluid cap, coolant overflow cap, brake fluid cap, and power steering fluid cap.

These engine bay caps are easy to use. Just remove your old factory caps and replace them with these Billetworkz caps. They're designed to fit perfectly in your 2015 - 2021 Subaru STI. When installing, make sure to tighten them properly but don't over - tighten to avoid damage. For maintenance, you can clean them with a mild soap and water solution. Avoid using abrasive cleaners as they might scratch the anodized finish. Keep them dry after cleaning to prevent rust or corrosion. If you notice any signs of wear or damage, it's a good idea to replace them right away.
