Frequently Asked Questions

How often should I replace my spark plugs?

Replacement intervals depend heavily on the spark plug material. Standard copper plugs usually need replacement every 30,000 miles. Platinum plugs typically last 50,000–60,000 miles. Premium Iridium and Double Iridium plugs, like those from Bosch and NGK, are often rated for 80,000 to 100,000 miles.

What is the difference between single and double Iridium plugs?

Single Iridium plugs have an Iridium center electrode and a standard nickel or platinum ground electrode. Double Iridium plugs (like Bosch OE Fine Wire) feature Iridium or Platinum on both the center and ground electrodes, maximizing wear resistance and extending the plug's lifespan significantly.

Can I install high-performance spark plugs in a standard engine?

Yes, generally. High-performance plugs (like Iridium IX) offer better ignitability and durability than standard plugs, which can slightly improve efficiency and throttle response even in a standard engine. However, always ensure the plug’s heat range and thread specifications match your vehicle’s requirements.
