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
  • E3 Automotive spark plugs are warranted to be free of defects in material and workmanship for a limited 5 years or 100,000 miles from the date of purchase. This 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 cover by the warranty.

Installed and had no problems for 25,000 miles. Then one came apart on me(when I was 150 miles from home at 1:00 in the morning in a snow storm). The ceramic came loose from the main base and I had no options but to drive it home that way. This caused the ceramic to beat the coil to death and loosen the base beating about half of the threads out of the head. I replaced the plug and got the new to tighten in the remaining threads. Don't!!! drive your vehicle when the plug falls apart. The ceramic and base both looked ok they just wouldn't go back together. I suspect the ceramic hammered the hole in the base closed a little.

        The acid test would be if I'd done a dyno pull with a new set of 'standard' plugs then another pull with these. I did not do that.
        I can tell you they work as spark plugs - how much of the hype you believe is up to you.

              I'm just an average everyday driver. I fell for their claim of better fuel efficiency. If you are planning to buy this plug to improve your mileage, don't bother. Buy the regular plugs for your vehicle at a MUCH cheaper price. My mpg is the same as before in my 2008 Hyundai Elantra. Happy New Year!!!
