E3 Spark Plugs

The basic spark plug construction hadn't changed that much since the original plugs were used by Henry Ford in 1904. Most drivers would probably argue that changes are needed. They just didn't hear about E3. Based in Ponte Verda, Florida, E3 is a home to the advanced DiamondFire Technology spark plugs. The newly developed design of the components is made for improved horsepower, increased fuel efficiency, and reduction in engine emissions.

    But how did the manufacturer achieve such outstanding results? With decades of successful experience in spark plug engineering and development, the principals of E3 arrived at a decision that the key to producing a better quality spark plug did not lie in the use of superior grade materials, such as platinum or iridium. Instead, they discovered an efficient new approach to the design of the spark plug's electrode to allow for improved ignition of raw fuel inside the engine's combustion chamber.

    1997 Jaguar XJ-Type | Posted by Jerrard | (Lakewood, CA)

    97 Jaguar XJ6. Don't need to say anymore. Get all that I need from this car. Just want to keep it this way. Birthday present of 6 E-3 plugs and air filter. Right off the bat the idle was smoother than before. From a retired mechanic, a happy face. Went for a test run and I could feel the bite of the great white shark. Still happy. Next day I drove from Lakewood, Ca to Ojai, Ca. All the back roads and 150 from Santa Paula to Ojai. Better MPG. Hills and hairpin curves. Where did this car come from. I'll fall in love again. Won't tell the wife it's a car. Uphill acceleration was unlike anything I ever had. Chevy Vega V8 to Jag xke. Blue printed Dodge Dart 340 my money maker back in the day; Happy with your plugs. On the track I can still do 155 mph. a special racing chip added for extra horse power. Thanks for listening to my story. From the 60 year old teenager.
