Using this Torque Solution oil cap is easy. Just take off your old oil cap and screw on this new one. It should take only a few minutes. Make sure to hand - tighten it properly. As for maintenance, there's not much you need to do. Since it's anodized, it won't rust or tarnish easily. But you can clean it with a mild soap and water solution every now and then to keep it looking good. Remember, in California, due to Proposition 65, there are warnings about chemicals.
