Traditional copper spark plugs have been used for decades. They are relatively inexpensive but have a shorter lifespan and lower performance compared to iridium and platinum plugs.
Iridium plugs feature a fine electrode made of iridium, a highly durable and corrosion-resistant metal. They offer improved ignitability and longer service life compared to copper plugs.
Platinum plugs utilize a platinum electrode, which provides excellent durability and resistance to wear. They are a step up from copper plugs but generally have a shorter lifespan than iridium plugs.

The lifespan of spark plugs can vary depending on several factors, including the type of spark plug, driving conditions, engine design, and maintenance practices. Here’s a general guideline for the lifespan of iridium and platinum spark plugs:
1. Iridium Spark Plugs:
2. Platinum Spark Plugs:
It’s worth mentioning that these mileage ranges are general estimates, and some vehicles may experience shorter or longer spark plug life depending on individual circumstances. It’s always a good idea to consult your vehicle’s manual or follow the recommendations of your vehicle manufacturer for the specific spark plug replacement intervals.
Regular maintenance and inspection of the spark plugs are essential to ensure optimal performance and longevity. If you notice signs of poor engine performance, misfires, or rough idling, it may indicate that the spark plugs need to be replaced or serviced.
Both iridium and platinum spark plugs are viable options, offering advantages over traditional copper plugs. Iridium plugs excel in terms of longevity and performance, providing improved ignitability and a longer service life.
Platinum plugs offer good performance and durability at a more affordable price point. When choosing between the two, consider factors such as your budget, vehicle requirements, and personal preferences.
Consulting your vehicle’s manual or a trusted mechanic can help you make the best decision for your specific vehicle.
