Are E3 Diamond Fire spark plugs good?
E3 made a lot of claims of more power, smoother running, and better gas milage. Upon opening these plugs the first thing I noticed is that the end of the spark plug is much longer than the NGK plugs. They are 3/16″ longer than the stock NGK spark plugs therefor they will stick 3/16″ further into the combustion chamber.

What are E3 spark plugs?
This e3 spark plugs review puts a lot of prominence on the ground electrode design, which has a US patent number 6,495,948. The entire patent shows precise combustion of the steam or combustible air of the car that is had, presenting higher pressures in the cylinder for precise and direct power.
How does the E3 Diamondfire configuration work?
There are three main performance components that determine how the E3 DiamondFIRE configuration works: The first component mimics surface gap spark plugs (like the type used in rotary engines) which directs the flame kernel to the piston (or rotor) more directly than traditional J-wire designs.
Why is the E3 electrode on a jet engine elevated?
Since the initial combustion wave leaves the spark area at supersonic speeds, the elevated edge of the E3 electrode provides somewhat of a chimney effect as the next air-fuel mixture enters the spark zone.
Why are the electrodes on a spark plug sharpened?
Since the spark itself occurs only when an avalanche of electrons migrates from the two electrodes (cathode to anode), sharp edges are better at initiating migrations, and accelerated electrons collide inside the spark zone.
