Iridium spark plugs are known for their longevity, often lasting up to 100,000 miles or more, which is significantly longer than traditional copper spark plugs, which typically last about 20,000 miles. This longevity makes iridium spark plugs a popular choice for many vehicle owners looking to reduce maintenance frequency.
How Long Do Iridium Spark Plugs Last?
Iridium spark plugs are designed to last between 60,000 to 120,000 miles, depending on the vehicle and driving conditions. This durability is due to the hardness and high melting point of iridium, a metal that withstands extreme temperatures and wear. In contrast, copper spark plugs generally last about 20,000 miles, while platinum spark plugs can last up to 60,000 miles.
What Affects the Lifespan of Spark Plugs?
Several factors influence the lifespan of spark plugs, including:
- Driving Habits: Frequent short trips can cause spark plugs to wear out more quickly.
- Engine Type: High-performance engines may demand more from spark plugs, reducing their lifespan.
- Maintenance: Regular engine maintenance can help extend the life of spark plugs.
- Fuel Quality: Poor fuel quality can lead to deposits that affect spark plug performance.
Why Choose Iridium Spark Plugs?
Iridium spark plugs offer several advantages over other types:
- Longevity: Last longer than copper and platinum plugs, reducing replacement frequency.
- Performance: Provide better ignition and efficiency, enhancing engine performance.
- Fuel Efficiency: Can improve fuel economy due to more efficient combustion.
