Using your Verus FHS oil cap is straightforward. First, gather simple hand tools. Then, remove the existing plastic OEM oil cap from your Subaru engine (fits WRX 2002 - 2024, STI 2004 - 2021, BRZ 2013 - 2024). Take your new Verus cap, which is made of 6061 - T6 aluminum and has a laser - engraved logo. You can adjust the logo orientation as you wish thanks to the two - piece design. Install the new cap using the included hardware. When it comes to maintenance, since the anodized parts can fade over time due to engine bay heat, try to park your car in a cool place when possible. If you notice significant fading, unfortunately, there's not much you can do to reverse it, but the cap will still function well.
