E3 – DiamondFIRE Automotive Spark Plug: More Power, Saves Gas (Part No.E3.72)

DiamondFIRE Automotive Spark Plug: More Power, Saves Gas

from

$6.49
The Spark Plugs are the product of years of fundamental research in the combustion field. The unique patented electrode configuration of these new The spark plugs increases the amount of combustion pressure created during each power stroke of an engine, which results in a marked increase in power output, fuel economy, and reduced emissions in all gasoline engines. E3.72 is an 18mm, 0.430 reach plug with a taper seat. It primarily fits Ford applications from the 50s to 90s. The automotive plugs have three legs securing the Diamond FIRE electrode to the shell. This allows for excellent heat transfer, and helps to create more turbulence in the cylinder. The patented Diamond FIRE side wire is proven to increase power, reduce fuel consumption and improve hydrocarbon emissions in long-term use.

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 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.
  • Patented Electrode Configuration: The unique patented electrode design of the E3.72 spark plugs increases combustion pressure, resulting in higher power output and improved fuel economy.
  • Enhanced Heat Transfer: The three legs securing the Diamond FIRE electrode to the shell ensure excellent heat transfer, contributing to better engine performance and longevity.
  • Reduced Emissions: The E3.72 spark plugs help improve hydrocarbon emissions, making your vehicle more environmentally friendly over long-term use.
  • Compatibility with Ford Engines: Specifically designed to fit Ford applications from the 50s to the 90s, the 18mm, 0.430 reach plug with a taper seat ensures a perfect fit for a wide range of classic and vintage Ford vehicles.
