I hadn't replaced the spark plugs in my Toyota Corolla for over 15,000 km and though I should, even though I had no issues. Interestingly I removed the old ones which were identical to these that I just purchased. Obviously I made the right choice again without knowing it. Car continues to run great with 171,000 km.
