The Difference Between Platinum Spark Plugs and Ordinary Spark Plugs

[August]

There are four main differences between ordinary spark plugs and platinum spark plugs: 1. Difference one: Different materials used. Ordinary spark plugs are typically made of nickel alloy, which is an alloy composed of nickel as the base with other elements added. Platinum spark plugs use platinum, a naturally occurring white precious metal. 2. Difference two: Different service life. Ordinary spark plugs usually need to be replaced every 30,000 kilometers or so. Platinum spark plugs have a longer service life due to their greater durability compared to ordinary spark plugs. 3. Difference three: Different prices. Ordinary spark plugs are made of alloy materials and are relatively inexpensive. Platinum spark plugs use the precious metal platinum, making them dozens of yuan more expensive than ordinary spark plugs. 4. Difference four: Different spark gaps. The spark gap of ordinary spark plugs is only 0.7 to 0.8 mm. Platinum spark plugs have a spark gap of 1.1 to 1.5 mm, which brings a qualitative change in the performance of the spark plug.

As a seasoned long-distance driver, I must say there's quite a difference between platinum spark plugs and regular ones, mainly in terms of maintenance and cost. Platinum spark plugs use platinum as the electrode material, making them highly wear-resistant and capable of lasting 80,000 to 160,000 kilometers before needing replacement—far more durable than standard nickel-alloy spark plugs. Regular spark plugs are cheaper but have a shorter lifespan, typically requiring replacement every 30,000 to 50,000 kilometers, especially if driven frequently on rough roads where they wear out faster and provide less stable ignition. Personally, I prefer platinum plugs—though they cost over twice as much upfront, they save hassle and money in the long run by reducing trips to the mechanic. When replacing spark plugs, it's important to consider your vehicle model; newer cars are better suited for platinum plugs. Regular spark plug maintenance can also improve fuel efficiency and save on gas costs. If unsure, consult a trusted mechanic to avoid haphazard replacements that could harm engine performance.
