Description

The E3.56 Premium DiamondFIRE Automotive Spark Plug is engineered to deliver peak performance and efficiency for your vehicle. Featuring E3's patented DiamondFIRE edge-to-edge ground electrode, it ensures a faster, more complete burn for smoother acceleration and idle. The innovative 'diamond-shaped' side wire electrode enhances combustion by igniting the air/fuel mixture more quickly, resulting in a larger flame kernel and improved power output—up to 6% on average. Designed with nickel center and ground electrode tips, this spark plug offers durability and consistent performance. Its cleaner-burning combustion reduces engine carbon deposits and promotes fuel savings, making it an eco-friendly choice. Pre-gapped at the factory for hassle-free installation, this spark plug is a perfect blend of advanced technology and convenience, ensuring your engine runs at its best.
