Shopping for Spark Plug

Spark Plug Shopping Info

What Is a Spark Plug?

Spark plugs are some of the most important parts of any vehicle — you can’t even start your car without them. The spark plug is responsible for creating the initial spark, very similar to a controlled bolt of lightning, that is necessary to start the combustion process.

How Much Does a Spark Plug Replacement Cost?

Aftermarket spark plugs can cost anywhere between $5 to $100 depending on the quantity of the spark plugs you’re buying and the electrode material. Platinum and iridium-tipped spark plugs usually cost a little more than standard nickel-alloy spark plugs. Labor costs, on the other hand, can range from $40 to $250 depending on your area and the exact make and model of your vehicle.
