Spark plugs are one of the most important components of ICE cars. They are located in the cylinder head and provide a spark of electricity that ignites the air and fuel mixture and powers the vehicle. Just like any other car part, they will need to be replaced over time. You can replace them yourself and save money and time as opposed to visiting a mechanic. Here are the best spark plugs currently available on Amazon — prices will vary depending on the make, model and year of your vehicle.

How do I know if my spark plugs are bad?

There are a few signs that your plugs need to be replaced. The most common are issues starting the car, rough idling, sluggish acceleration, bad fuel economy, engine knocking and misfires.

How often should spark plugs be changed?

The change intervals of spark plugs can vary depending on the plugs. According to Mansfield Motor Group, “Ordinary copper and nickel spark plugs should be changed every 30,000 to 50,000 miles, unless otherwise suggested by the spark plug manufacturer. Platinum and iridium spark plugs tend to last longer than standard copper and nickel spark plugs. Expect to change them every 60,000 to 150,000 miles unless otherwise noted.”
