E3 – DiamondFIRE Automotive Spark Plug: More Power, Saves Gas (Part No.E3.44)

DiamondFIRE Automotive Spark Plug: More Power, Saves Gas

from

$6.99
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. E3.44 is a 14mm, 0.708 reach plug with a taper seat. It fits domestic applications from the mid-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 E3.44 spark plugs increases combustion pressure, resulting in enhanced power output and improved fuel economy.
  • Superior Heat Transfer: The three-leg design securing the Diamond FIRE electrode to the shell ensures excellent heat transfer and creates more turbulence in the cylinder for optimal performance.
  • Compatibility: The E3.44 spark plug is a 14mm, 0.708 reach plug with a taper seat, fitting domestic applications from the mid-90s.
  • Environmental Benefits: By improving combustion efficiency, these spark plugs help reduce emissions, contributing to a cleaner environment.

Mr. Gasket – Hei Advance Curve Kit (Part No.929G)

Hei Advance Curve Kit

from

$16.49
One of the best, and sometimes missed tuning tricks is not to just optimize your initial timing, but to bring in timing advance more quickly than the stock distributor can allow. Bringing timing more quickly than stock can provide substantial increases in both torque and horsepower depending on your combination.This is done by changing the springs under the cap. This kit includes three sets of springs which can be used in different combinations to provide full advance sooner than stock. Use lighter springs to bring the advance more quickly, and heavier springs to bring it in more slowly. Two new weights with nylon bushings are also included as are instructions to help with installation. Springs are color code as follows: Light Springs – Black Medium Springs – Silver Heavy Springs – Gold

Product Features:
  • Brings in timing more quickly than stock for more torque and horsepower
  • Includes three sets of springs to allow for a wider range of custom tuning
  • Instructions included to help with installation
