      Spark Plug Socket

      Enhance Engine Performance With a New Spark Plug Socket

      Whether you drive a heavy-duty, full-sized pickup truck; a compact, fuel-efficient car; or anything between, starting it comes down to a little part that produces a tiny bolt of electricity. The small but mighty spark plug gets the engine's pistons moving, transmits heat from the combustion chamber into the cylinder head and is a key factor in engine performance. When one goes bad, count on AutoZone for the lowest prices on spark plug sockets to get you back on the road.

      Simple Yet Complex

      Spark plugs are designed to withstand heat and pressure, as well as burn off contaminants. These seemingly simple parts are actually a complex design that includes multiple features to make them work properly, including ribs, insulator, seals, central electrode, ground electrode, gasket and much more.
      When it's in good shape, your engine should fire up and perform at an optimal level. After 20,000 to 40,000 miles, depending on the vehicle, there might be signs of slower performance that could be related to the spark plug. While a vehicle that won't start is a good indicator that it needs to be replaced, symptoms like slow acceleration, reduced fuel economy, vibrating when idling or sudden power surges may signal that the part is failing.

      Quality Socket Replacement

      When it is time for replacement, AutoZone has the best spark plug sockets for cars and trucks. Since the spark plug serves an imperative role for your vehicle, it's vital to use the right tools for the job. These sockets are designed to help properly remove and fit spark plugs, keeping them free of damage. They typically have a rubber insert that works to keep the plug secure and protect it during use. Most are made from steel that is treated to ensure extended durability.

      Easy To Use

      These sockets are designed to be easy to use, just like a standard socket. When it comes to spark plugs, not just any socket will do. They have a hexagon, often called hex, which serves as the contact point for the socket wrench. The hex determines the size of socket needed for proper installation. The most common sizes are 5/8 inches and 13/16 inches, but they also come as small as 5/16 inches and over 1 inch. If the wrong size is used, it could result in damage or make removal nearly impossible. To determine the size needed, you can measure the spark plug's hex, along with the existing socket, boot and wrench size. It can also be carefully removed and taken to an AutoZone expert to ensure you get the right part.
      Although spark plugs are designed to be rugged and durable, nothing lasts forever. When it's time to search for “spark plug sockets near me,” count on your local AutoZone or AutoZone.com to provide the assistance and parts you need with excellence and great prices.
