E3 – DiamondFIRE Automotive Spark Plug: More Power & Fuel Efficiency (Part No.E3.64)

DiamondFIRE Automotive Spark Plug: More Power & Fuel Efficiency

from

$8.49
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 quickly igniting the air/fuel mixture, resulting in a larger and faster flame kernel. This translates to improved power output by up to 6% on average and significant fuel savings, while also reducing engine carbon deposits for a cleaner burn. Constructed with durable nickel for both the 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. Upgrade to this advanced spark plug for enhanced engine performance, better fuel efficiency, and a cleaner, more reliable ride.

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.
