How Many Spark Plugs Does a Car Generally Have?
1 Answers
In general, a car will have as many spark plugs as it has cylinders, but there are exceptions. Most four-cylinder cars have four spark plugs, and six-cylinder cars have six spark plugs. If a spark plug is damaged, it can directly cause issues such as electrical leakage in the vehicle's ignition system, increased fuel consumption, and reduced power. The most significant problem is difficulty in starting, which affects the normal operation of the vehicle. Severe spark plug erosion, including scarring at the top, damage, or melted and eroded electrodes, indicates that the spark plug is damaged and should be replaced. Spark Plug Location: Spark plugs are installed on the side or top of the engine. Early spark plugs were connected to the distributor via ignition wires, but over the past decade, most car engines have switched to direct connection between the ignition coil and the spark plug. Spark Plug Replacement Interval: Under normal maintenance conditions, spark plugs should be replaced every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine, so it's recommended to follow the owner's manual. Typically, platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers.
