Frequently Asked Questions (FAQs)
1. Can I use a regular socket for spark plugs?
No, regular sockets should not be used for spark plugs. Spark plug sockets have rubber isolators inside to absorb vibration and protect the spark plug. Regular sockets lack this feature and may result in breakage during spark plug replacement.
2. What are the two sizes of spark plug sockets?
The two most common sizes of spark plug sockets are 5/8 inch and 13/16 inch. However, there are other sizes available, each with its own specific applications.
3. What tools do I need to change out spark plugs?
To change spark plugs, you will need a feeler gauge, a spark plug extension, a socket/ratchet wrench set, and optionally, a torque wrench and anti-seize lubricant. You may also consider using a rubber hose or rubber gloves for grip and protection against grease and engine dirt.
4. Will a 9/16 spark plug fit a 14mm?
No, the correct size for spark plugs is 14mm. While a 9/16 spark plug socket can be used, it is recommended to use a 14mm spark plug socket with a rubber lining to ensure proper fit and avoid potential issues.
