Installing the right spark plugs makes a crucial difference in the way your vehicle's engine performs. Vehicles with high-performance engines naturally produce more heat, so they utilize colder plugs. Cold plugs are designed with more contact area, so they transfer more heat away from the tip of the spark plug. Conversely, hot spark plugs are recommended for vehicles that are driven slower and for shorter distances. These hot spark plugs are designed to reduce heat transfer and keep the tip of the spark plug insulated. Using spark plugs that burn too cold for your engine can result in sluggish engine performance—resulting in carbon fouling that requires you to replace or clean your spark plugs—whereas installing spark plugs that burn too hot for your ride can lead to overheating.

Whether you're searching for a hot or a cold spark plug for a classic automobile or a contemporary vehicle, AutoZone provides numerous plugs that are custom-made for your ride. So, whether you're looking for Ford Mustang spark plugs or spark plugs for Honda Accord, you're sure to find the perfect match when you shop our unbeatable selection. We also carry plugs from leading industry vendors, so you can rest assured that you're receiving a high-quality product that's designed to last for the long haul.
