5 Best Spark Plugs in 2018

Top 5 Spark Plugs to Ignite your Engine in 2018

The spark plugs are an integral detail in every vehicle. Fortunately for every car owner, they are quite affordable and easy to replace. Since there is nothing particularly difficult in maintaining this part, many drivers prefer to handle the replacement on their own.

There are a few important facts to remember when it comes to the spark plugs in the car.

First of all, the sparks tend to move from the sharpest notch on the center electrode to the sharpest point on the side one. Therefore, you need to have a plug that would be able to retain the sharp edge all the way through. Namely, the nickel alloy electrodes used in the traditional copper spark plugs have lower melting temperature than the platinum and iridium ones. Next, the diameter of the center electrode determines the required voltage. In other words, the larger the diameter, the more power will be necessary to ignite the spark.

Usually, the choice of spark plugs shrinks to the four most common types:

  • copper spark plugs,
  • platinum spark plugs,
  • iridium spark plugs, and
  • the plugs made of some other material.

This car part is manufactured by several different brands, so it can be quite challenging to decide which one fits your car the best.

Choosing the Best Spark Plug


The market is packed with spark plugs. Before making a purchase, you must determine which one is going to be right for your vehicle. The best piece of advice in this matter is to keep going for the plugs that are recommended by the owner’s manual for the engine. The manufacturer is a reliable source of information when it comes to choosing the most suitable details for the car part.

You might have heard of the slight changes in the temperature can impact the overall performance of the spark plug. Sometimes, it can be the case, but in general, the factory-specified plugs are much better for the engine.

The last piece of advice is to replace the plugs before the wear. If you wait until the end of the full-service cycle, you’ll make your life more complicated. After the end date, the plugs can compress the cylinder head, and thus it will be harder to remove them. Likewise, the reduced gas mileage caused by the expiring spark plugs will cost you more than the set of new ones.
