Spark plugs are really darn cheap! And changing spark plugs on your car is one of the easiest maintenance jobs that you can DIY on your vehicle. However, the number of spark plugs in a car depend upon its engine.
The most four-cylinder engine has 4 spark plugs, those with six cylinders have 6 plugs, and so on. Additionally, those engine classified as twin-spark (like those of the racing-type cars) has 2 spark plugs per cylinder. So, if you have a twin-spark V6 engine, it follows that you need 12 spark plugs, and so on and so forth.
If you sum up this numbers, you will end up having lots of spark plugs in a single car. Though they are basically cheap to buy, spark plugs need to be of high-quality to have longer service. An average plug serves you well within the 30,000 to 50,000 mileage, but other brands may take you further than this with a minimum of maintenance.
