    • Product Details

      Part No. E3.44

      Warranty Details (5 YR REPLACEMENT IF DEFECTIVE)

      E3 Spark Plugs are the product of years of fundamental research in the combustion field. The unique patented electrode configuration of these new E3 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.

      Product Features:

      • E3's DiamondFire edge to edge electrode provides maximum performance with increased efficiency and a faster more complete burn
      • Smoother Acceleration & Idle - The faster flame initiated by the E3 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 by 6% on average in the typical operating ranges
      • Efficiency - E3 "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 longer flame kernel
      • Emissions - E3 provides a cleaner burning combustion, which translates into fuel savings and reduced engine carbon deposits
      • E3 Spark Plugs are pre-gapped at the factory to meet O.E. requirements
      • Warranty does not cover plugs installed in any modified engine or used in any racing, aircraft, or commercial application. Spark plugs damaged by abuse, accidents, or improper installation or applications are not covered by this warranty.
