Frequently Asked Questions
How often should I replace my spark plugs?
Replacement intervals vary significantly based on the plug material and engine type. Copper plugs typically last 30,000 miles or less. Iridium and Platinum plugs can last 60,000 to 100,000 miles. Always check your vehicle or equipment owner's manual for the recommended service schedule.
What is the difference between a magnetic and a rubber insert socket?
Both are designed to hold the spark plug. Magnetic sockets (like the LEXIVON) use a strong magnet for retention, offering durability and a secure grip. Rubber insert sockets use a rubber grommet, which can sometimes wear out or slip, but are generally less expensive.
Do spark plugs need to be gapped before installation?
While many modern iridium/platinum plugs are pre-gapped, it is always best practice to check the gap against your engine's specification using a gap tool. Never attempt to gap fine-wire iridium or platinum plugs unless specifically instructed, as you can damage the electrode.

Maintaining a healthy ignition system is non-negotiable for engine reliability and performance.
