Often, manufacturers recommend these plugs with newer models, especially if it has a coil-on-plug ignition. Because of this, the carbon buildup is minimal. Because platinum is a stronger metal, the plug is going to last longer than the copper alternative.Īdditionally, these plugs create more heat.

The single platinum plug has a similar design to the copper plug, other than the center electrode is made from a platinum disc welded to the tip. These plugs can last up to four times as long as the copper plug, but you are going to pay that much extra for them. These deliver more firepower for vehicles that operate in extremes, whether the temperatures are high or speeds are at a maximum. There’s also the option to choose double iridium plugs. If you did, you would notice a significant decrease in performance.

If that is what the manufacturer recommends, you definitely don’t want to downgrade to copper or a platinum plug. Newer cars often come with iridium spark plugs. However, these benefits create one of the highest price tags on spark plugs. The center electrode is small, so less voltage is needed to make the spark. Iridium material is more durable and harder than platinum, which we will review in a minute. Still, many manufacturers recommend using this type of plug, so it’s best to follow the advice given in your owner’s manual. For this reason, you have to replace these spark plugs sooner than any other. Of all spark plug types, this one has the largest diameter, requiring the most amount of voltage to create a spark.īecause nickel alloy is a soft material, it’s not going to be durable. The center electrode has a copper core with a nickel alloy coating. Let’s look at the pros and cons of the top plug types to determine what might suit your car the best. The differences have to do with longevity, overall performance, and the cost spent for each. The main spark plug types include copper/nickel, iridium, platinum, and double platinum. Spark plugs are classified by the material they are made from. We also answer a few of your top spark plug questions. You’ll understand the pros and cons of each, allowing you to make a decision when it’s time for your next tune-up. In this guide, we look at the differences between all of the spark plug types. To complete the job right, you need to know the different types of spark plugs available for your vehicle. This essential tune-up keeps the engine running at its best. Regular car maintenance involves changing the spark plugs occasionally.
