How often to change spark plugs

Picture this: you’re cruising down the highway, enjoying the open road, when suddenly your car’s engine stutters. You pull over, pulling out your trusty owner’s manual for advice. Among various maintenance tasks listed is the often-overlooked spark plug change, but the recommendation is vague. You can’t help but wonder–how often should I actually be changing my spark plugs to keep my car running smoothly and prevent those unexpected hiccups?

Typically, spark plugs should be changed every 30,000 to 100,000 miles, depending on the type of spark plugs used and your vehicle’s specific requirements.

When considering how often to change spark plugs, several factors come into play, including the type of spark plugs installed (copper, platinum, or iridium), the manufacturer’s recommendations, and your driving habits. Standard copper spark plugs generally need replacement around every 30,000 miles, while platinum and iridium spark plugs tend to last longer, often between 60,000 and 100,000 miles. Regular maintenance could allow you to extend the lifespan of your spark plugs, but be mindful of signs that they may need replacing sooner, such as difficulty starting your engine, poor fuel economy, or engine misfires. Keeping an eye on these indicators, along with regular maintenance checks, can help ensure that your spark plugs–and your vehicle–perform at their best.
