about 100,000 miles
FACT #4: YOU SHOULD CHANGE SPARK PLUGS EVERY 100K MILES OR SO. So, if good spark plugs are the key to avoiding these issues, how long do spark plugs last, exactly? The general rule of thumb about how often to change spark plugs is that they should be replaced after about 100,000 miles of driving.
Can spark plugs last 5 years?
When your engine is functioning correctly, spark plugs should last between 20,000 and 30,000 miles. The U.S. Federal Highway Administration clocks Americans’ average annual mileage at 13,476. Break this down into spark-plug life expectancy, and it comes to between 1.5 and 2.25 years.
- How long do spark plugs last?
- In terms of lifespan, the use life you enjoy will depend in the type of plug used in the engine. Normal copper plugs only last about 20,000 miles. However, using platinum plugs can give you 60,000 miles of use. Other types can last up to 100,000 miles. Of course, it can be very difficult to tell if your spark plugs are beginning to wear out.
- How often should you change spark plugs on a Toyota?
- For example, Toyota recommends changing the plugs every 120,000 miles on a Corolla, RAV4 or 4Runner, but every 60,000 miles on an 86 coupe, which was developed with Subaru and uses a Subaru engine. Ford advises to change the plugs at 100,000 miles on an F-150, Explorer and other models under “normal” driving conditions.
- Do spark plugs need to be replaced?
- Poor fuel economy is another indication the plugs or spark plug wires likely need replacing. Although modern spark plugs last considerably longer than those produced 30 years ago, they don’t last forever and need to be replaced at regular intervals. It’s best to check the owner’s manual. What Does a Spark Plug Do?
- What happens if your spark plugs are bad?

Why do spark plugs last so long?
New spark plugs have tips made from precious metals such as platinum and iridium, which can withstand heat better than old ones tipped with copper alloy. Cars can now go 60,000 to 100,000 miles between changes instead of 10,000 miles, or once a year, on older plugs, automakers say.
- What happens when a spark plug is too short?
- As the spark plug fires, minute amounts of the electrode evaporate. Eventually, it’s too short to create the spark needed to ignite the fuel/air mix.
- Why do spark plugs need to be changed?
- The primary reason that spark plugs need to be changed is due to wear and tear. As the spark plug fires, minute amounts of the electrode evaporate. Eventually, it’s too short to create the spark needed to ignite the fuel/air mix.
- How long do copper plugs last?
- The result is a rough running engine, skipping cylinders and other problems that cost you in performance and fuel economy. In terms of lifespan, the use life you enjoy will depend in the type of plug used in the engine. Normal copper plugs only last about 20,000 miles.
