The Premium DiamondFire Automotive Spark Plug is engineered to deliver exceptional performance and efficiency for your vehicle. Featuring E3’s patented Diamond Fire 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 quickly igniting the air/fuel mixture, resulting in a larger and faster flame kernel. This translates to improved power output – up to 6% on average – and better fuel efficiency, saving you money while reducing engine carbon deposits. Constructed with durable nickel center and ground electrode tips, this spark plug is built to last. Its gasket seat type ensures a secure fit, and the pre-gapped design eliminates the need for adjustments, making installation hassle-free. With its advanced technology, this spark plug not only boosts engine performance but also contributes to a cleaner, more efficient combustion process.

Product Features:

• E3’s Diamond Fire edge to edge ground electrode provides maximum performance with increased efficiency and a faster more complete burn.
• Smoother Acceleration & Idle – The faster flame initiated by the spark plug results in a more complete burn of the ingested fuel charge. More pressure is created against the piston more fuel is put to work
• Energy – Power output improved up to 6% on average in the typical operating ranges. Results will vary.
• Efficiency – The “diamond shaped” side wire electrode projects the combustion spark in a way that more quickly ignites the air/fuel mixture, thereby creating a significantly faster and larger flame kernel. The result is that more fuel is put to work durin
• E3’s patented Diamond Fire Technology provides a cleaner burning combustion, which translates into fuel savings and reduced engine carbon deposits
• The Spark Plugs are pre-gapped at the factory and cannot be adjusted.
