How often should platinum spark plugs be replaced?

[VanConnor]

Platinum spark plugs should generally be replaced every 60,000 kilometers. Below are the specific details: 1. The replacement interval should be analyzed flexibly based on actual conditions. If the vehicle is under warranty, strictly follow the replacement schedule specified in the maintenance manual. Failure to adhere to the manual's replacement guidelines may give the manufacturer grounds to deny warranty claims if engine issues arise. For vehicles out of warranty, spark plugs can be replaced every 40,000 to 50,000 kilometers. 2. Spark plugs are divided into two types: standard copper-core (nickel alloy) spark plugs and precious metal spark plugs (platinum, iridium). The main difference lies in the electrode material. Standard spark plugs have a service life of 30,000 kilometers, platinum spark plugs last up to 60,000 kilometers, and iridium spark plugs can endure up to 80,000 kilometers.
