Using these oil caps is easy. Just unscrew the old cap and screw on the new DRAG CARTEL K - SERIES cap tightly. Make sure it's well - seated to prevent any oil leaks. When installing, handle the caps gently to avoid scratching the anodized finish. For maintenance, clean the caps regularly with a mild soap and water solution. Avoid using abrasive cleaners as they can damage the anodized coating. Store the caps in a dry place when not in use to prevent corrosion.
