Which Material Spark Plug is More Durable?
2 Answers
Iridium spark plugs are durable. Advantages of iridium spark plugs: 1. Improve fuel efficiency. Iridium spark plugs can enhance fuel consumption in most cases. When using iridium spark plugs, the car is less likely to stall or misfire under various driving conditions, ensuring good combustion and achieving the goal of reducing fuel consumption. 2. Long lifespan: Many cars on the market use nickel alloy spark plugs, which have a relatively short lifespan, typically around 20,000 kilometers. In contrast, iridium spark plugs can last up to 60,000 to 80,000 kilometers. 3. Enhance engine performance: Compared to ordinary spark plugs, iridium spark plugs can improve engine performance, enhancing the car's acceleration. Iridium spark plugs provide sufficient ignition energy and stable spark points, thereby boosting the car's performance. 4. Save fuel consumption: High-quality iridium spark plugs can quickly ignite the combustion point. For example, well-crafted extreme iridium spark plugs on the market can ensure full combustion of fuel, thereby saving fuel. Steps to replace spark plugs: Open the engine hood, lift the plastic cover of the engine, and remove the high-voltage wires. Mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for external debris like leaves or dust and ensure they are cleaned thoroughly. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Install the removed high-voltage wires according to the firing order, and then secure the cover.
The material choice of spark plugs directly affects durability. I think the common types include copper, nickel alloy, platinum, and iridium. Copper is the cheapest but has the shortest lifespan, typically lasting only 20,000-30,000 kilometers before issues arise. Platinum is more expensive but more durable, capable of running over 100,000 kilometers, making it suitable for daily driving. Iridium is the top-tier option, featuring slender electrode designs and strong corrosion resistance, maintaining stable ignition even under high temperatures or harsh conditions, with a lifespan reaching 120,000-150,000 kilometers. I've personally used iridium spark plugs, which lasted five years without replacement, ensuring smooth engine operation and low fuel consumption. Material selection should also consider the vehicle's condition—for example, sports cars are best suited with iridium to reduce misfires. For regular family sedans, platinum is sufficient and offers good cost performance. Remember, durable spark plugs can avoid frequent repair hassles, so prioritize long-term benefits during maintenance.
