    Built For Better Performance. A fouling spark plug can ruin the great performance of your Ford Mustang. But, this E3 Premium Diamond Fire Electrode Spark Plugs is built to not just replace your old spark plug. Designed to create superior spark and provide better heat transfers, this spark plug is made to offer efficient and better performance. With this plug, you can enjoy improved fuel efficiency, fewer toxic emissions, cleaner combustion, and overall better performance.

    Reliable Design. The E3 spark plug features an edge-to-edge design that makes for faster flame propagation. This design ensures that the flame kernel is formed faster and allows for a complete and efficient combustion process. This results in a more complete burning of fuel/air mixture, which in turn allows for more power and a cleaner engine.

    Unquestionable Quality. Manufactured from high-quality materials, the E3 premium spark plug offers durability and long-lasting service. The spark plug features a tapered seat and has three legs so you can easily and properly secure the electrode to the shell. This makes the plug stable and able to provide better heat transfers. It is also designed to clean carbon deposits to prolong the plug’s lifespan.

    5-Year / 100,000-Mile Limited Warranty. This E3 spark plug is backed by a 5-year or 100,000-mile limited warranty, whichever comes first. This is a limited warranty and covers only defects in materials and workmanship. No damages caused by abuse, accident or improper installation or application will be covered.

    Application. This E3 Premium Diamond Fire Electrode Spark Plugs is specifically designed for use on 1979-1982 Ford Mustang 5.0L models, 1987-1993 5.0L models, and 1994-1995 GT models. "
