How many kilometers do platinum spark plugs need to be replaced?
2 Answers
Platinum spark plugs should be replaced at around 40,000 kilometers. Recommendations for replacing platinum spark plugs: Ordinary nickel alloy spark plugs need to be replaced every 20,000 kilometers or so; iridium spark plugs can be used for 60,000 to 80,000 kilometers before replacement. Notes on spark plugs: The replacement cycle of spark plugs is not calculated by time, but depends on the mileage driven by the car. There are two types of spark plugs. The first type, ordinary copper-core spark plugs, can be used for about 30,000 kilometers. The second type, which is relatively better, uses precious metal spark plugs. Platinum spark plugs can last 40,000 kilometers, while iridium spark plugs can last 80,000 kilometers.
Regarding the replacement of platinum spark plugs, I find this topic quite interesting as it's one of the common maintenance items. I've owned several cars that used platinum spark plugs, and generally speaking, they have a long lifespan, typically lasting between 80,000 to 160,000 kilometers before needing replacement. The key is to consider the specific condition of the vehicle. For example, I often drive on highways where spark plugs experience less wear, and mine lasted up to 120,000 kilometers without issues. However, if you frequently drive in city traffic with constant stop-and-go conditions, the ignition system is under more stress, and the spark plugs might need inspection as early as 80,000 kilometers. Worn-out spark plugs can affect fuel efficiency and power output. I once delayed replacing mine beyond the recommended mileage, and the acceleration became noticeably sluggish. After installing new spark plugs, the performance improved immediately. Remember, the vehicle's manual is the most accurate guide—requirements vary by brand or engine type, so don't rely solely on online advice. Timely maintenance ensures peace of mind and safety.
