Spark plugs are one of the most important components of internal combustion engine (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 most other car parts, they will need to be replaced over time. You can visit a mechanic or dealership service center to have them replaced or, to save money, you could buy them online, or from your favorite brick-and-mortar car parts store, and replace them yourself. Here are the best spark plugs currently available at Amazon — prices will vary depending on the make, model, and year of your vehicle.
