This is an OEM IAME X30 spark plug boot cap. The cap might be labeled PVL or Selettra, but they're exactly the same in function and quality.
Using this spark plug cap is easy. First, make sure your engine is turned off. Then, gently remove the old cap from the spark plug and replace it with this new one. When installing, ensure it's firmly attached to avoid any loose connections. As for maintenance, it's a good idea to check the cap regularly for any signs of wear or damage. If you notice cracks or other issues, replace it right away. Store it in a dry place when not in use to keep it in good condition.
