E3 – DiamondFIRE Automotive Spark Plug: More Power & Fuel Efficiency (Part No.E3.42)

DiamondFIRE Automotive Spark Plug: More Power & Fuel Efficiency

from

$8.49
DiamondFire Automotive Spark Plug delivers exceptional performance and efficiency with its innovative Diamond Fire edge-to-edge ground electrode design. Engineered for smoother acceleration and idle, it ensures a faster, more complete burn of the fuel charge, maximizing pressure against the piston and putting more fuel to work. With power output improved by up to 6% on average, this spark plug enhances energy efficiency while reducing engine carbon deposits thanks to its patented Diamond Fire Technology. The unique diamond-shaped side wire electrode ignites the air/fuel mixture quickly, creating a larger flame kernel for optimal combustion. Crafted with durable nickel center and ground electrode tips, it offers long-lasting reliability. Pre-gapped at the factory for hassle-free installation, this tapered seat spark plug is a smart choice for drivers seeking improved fuel savings, cleaner engine performance, and enhanced power output.

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.
