How long do Toyota factory spark plugs last?
The lifespan of Toyota factory spark plugs can vary depending on several factors. According to Toyota, the recommended replacement interval for spark plugs is typically every 120,000 miles for models like the Corolla, RAV4, or 4Runner. However, it’s important to note that spark plug life is not solely determined by mileage. Other factors such as fuel quality, engine timing, and ignition system health can also affect the lifespan of spark plugs.
It’s worth mentioning that different Toyota models may have different recommended replacement intervals for spark plugs. For example, the 86 coupe, which was developed with Subaru and uses a Subaru engine, recommends changing the spark plugs every 60,000 miles.
Ultimately, it is best to refer to the maintenance schedule provided in your vehicle’s owner’s manual or consult with a certified Toyota technician for the most accurate information regarding spark plug replacement intervals for your specific Toyota model.
