The Premium DiamondFire Automotive Spark Plug is engineered to deliver peak 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 projecting the spark to ignite the air/fuel mixture more quickly, resulting in a larger and faster flame kernel. This advanced design improves power output by up to 6% on average within typical operating ranges, while also promoting fuel savings and reducing engine carbon deposits. Crafted with durable nickel for both the center and ground electrode tips, this spark plug is built to last. Pre-gapped at the factory for optimal performance, it eliminates the need for adjustments, making installation hassle-free. With its cleaner-burning combustion and enhanced energy efficiency, this spark plug is a smart upgrade for drivers seeking improved engine performance and long-term value.

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.
