Spark Plug


You expect a quick fire up every time you turn your key over. AutoZone provides performance spark plugs that can help you achieve that smooth startup in any situation. The spark plugs AutoZone stocks are made from high-quality materials, reassuring your vehicle can deliver exceptional performance for miles to come.

Your vehicle is engineered to produce the perfect fuel air mixture, but unless you have the right spark plug to ignite that mixture, your engine won't produce power. Due to high-voltage current and many chemicals from combustion, your spark plugs can erode over time which causes a gap between the plug and the electrode. Spark plugs can also become fouled by carbon and oil buildup or poor fuel quality - preventing a spark for igniting. Avoid all of this hassle by checking out a top-notch performance spark plug from AutoZone. Our spark plugs can help turn your rough idle into a smooth ride and help your engine become more fuel efficient. For optimal engine performance, replace your spark plugs every 30,000 to 50,000 miles with our supply of trusted products.

We understand not every vehicle uses the same spark plug, that's why we stock custom-designed spark plugs for your specific year, make and model. Whether you need F150 performance spark plugs, a new performance spark plug for Tahoe or anything in between, AutoZone has the solution. In addition, you can save with our Free Shipping program.
