Check Vehicle Fit

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.

    I own a 2007 Grand prix 3800 series3 engine. I was amazed how much power the engine gained. The fuel comsumption was better then the AC Delcos it came with.

    Comments about E3 Premium DiamondFIRE Electrode Automotive Spark Plug:

    For once a company that backs up the talk with flat out performance! Man I'm talkin bout performance you can flat out feel when you drive your vehicle. If it's noticeable in aten year old, six cylinder in mymommy-mobile minivan, I can only imagine what kind of gains you would get from a high performance V8 or a turbo engine. And just to be clear everything else in the ignition system is the same. Actually one of my wires is bad( terminal pulled off during R&R) and it still runs better than before with all six cylinder firing.Don't believe me try'em. You won't be sorry . I promise.

      These spark plugs deliver everything they promise in their ads; increased horsepower, better fuel economy and long life. I run them in every vehicle that I have from motorcycles to everyday cars to race cars.I no longer use any other brand.

          A:

          With reference to your inquiry on this E3 Premium DiamondFIRE Electrode Automotive Spark Plug (Part No. E3.44), the spark plug design forces air gap discharges, creates the preferred edge-to-edge spark path, allows free replenishment of the spark zone with a fresh fuel/air charge, and exposes the flame front more directly to the piston head than other plug designs. Sparks naturally follow edge paths as they leave an object. The E3 design presents multiple sharp edges to the center electrode. Sparks flow between these edges at lower voltages, facilitating easier discharge than standard designs. By forcing air sparks, the resistance to fouling is greatly increased in the E3 spark plug. This lowers the self-cleaning temperature of the spark plug, allowing colder heat ranges to be used if desired. E3's distinctive spark plug design has proven, in testing in a range of engines, to simultaneously increase engine power output, reduce gasoline consumption, decrease hydrocarbon and carbon monoxide emissions from the engine and materially extend the life of the spark plug.

      • Q:

        How would you set or check for specified gap?
        Asked on 4/18/2013 by NotMeAgain from NW-JaxFLA

        • CUSTOMER CARE

          A:

          Here's how to gap your new spark plug: Use a feeler gauge to check the gap of the spark plug. Choose the correct wire based on the size of the gap. Run the wire between the two electrodes of the spark plug. The wire should catch on them as it passes through. Widen the gap, if necessary, by hooking the gauge on the ground electrode and tugging gently. Be careful that the gauge touches only the ground electrode and not the porcelain or the center electrode. Narrow the gap, if necessary, by pressing or tapping the ground electrode gently against a clean, soft surface. Check the gap and adjust it as necessary. For further assistance regarding the E3 Premium DiamondFIRE Electrode Automotive Spark Plug (Part No. E3.44), please provide the year, make, model and engine size of your vehicle. For more information, please feel free to call us at: 1-877-238-2623 or visit the nearest Advance Auto Parts store and one of our Parts Pros will gladly assist you with any questions or concerns you may have.

          be sure to check what the original specs are for your vehicle. The will not work if your vehicle calls for Iridium plugs. I found out the hard way.

          I saw an episode of "Horsepower TV" where they did a dyno test of these plugs and they do give better horsepower and gas mileage.
