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 spark plugs. 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.

    E3 Premium Performance Plug
    It's a spark plug so I don't worry about looks. When it comes to reliability and gaining performance I choose e3. Take out one plug at a time with a socket and slowly put them in hand tight until all in the engine block. You wouldn't want to rush it here.
