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.

Shop for Aftermarket Spark Plugs on CarParts.com

For your convenience, look no further than CarParts.com when you’re searching for an aftermarket spark plug for sale. With our wide selection of spark plugs compatible with different makes and models, it’s easy to find the best one for your vehicle right here.
