Good To Know

Q: How does this tool prevent damage to the piston? A: The end of the bolt is smoothly rounded to ensure it makes contact with the piston head without leaving scratches or dents.

Q: Can this tool be used on 14mm spark plug holes? A: This specific model is threaded for 18mm holes, so a different size or adapter would be required for smaller ports.
