Product Description
E3 has taken the best features from traditional spark plugs, such as cut-back ground electrodes and surface gaps, and combined them to create a new ground electrode design. Surface gap plugs present the flame kernel to the piston (or rotor) more directly, reducing the travel time from the spark to the combustion gases (Although this difference is only measurable in hundred-thousands of a second, at 5000 RPM, they can add up). This avoids the "doughnut" shaped flame front created by standard spark plug electrodes. This is achieved in the E3 design through the open section at the top of the ground electrode. E3 spark plugs combine the benefits of additional sharp electrode edges with a cut-back electrode design used on some racing spark plugs. The increase of available edge-to-edge surface area encourages a more rapid spark discharge while also reducing quenching and shadowing. The three legs that support the special geometry of E3's automotive plug ground electrode aid in heat dissipation for longer electrode life. The center electrode on E3 spark plugs is created from a nickel alloy with a copper center core for both improved conductivity as well as heat dissipation.

I purchased these plugs to use in my 98 Saturn SL2. The first thing to do is inspect the plugs before installing them. They're made in a country whose quality control is suspect. The finished product isn't the best.
The threads on one of the plugs was damaged to the point where I had to dress it with a file first before installing it. If not, it could've cross threaded the head which would have been disastrous!!!
The plugs come already gapped. There were some variances in the gaps. I tried adjusting them but was unable to. The plug's design makes it very difficult if not impossible to do so. Since the variations were so slight, I felt it would not be an issue and decided to install them as is.
I debated on whether or not to use anti seize and eventually decided against it. The website for the spark plug doesn't really recommend it. It says that the threads are nickel plated which help to resist seizing and galling.
I just installed the plugs yesterday. The car seems to start up faster and has more pep when you hit the throttle. The old plugs that were removed were relatively new (5,000 miles on them) and in good condition so I don't think the improvements were a matter of worn plugs being replaced with new plugs. Even so, those things are hard to measure and open to the power of suggestion. The real test will be the miles per gallon, which I will be evaluating and reporting on after driving for approx. one month.
Stay tuned!!!
Update: It's one month and 1,200 miles later and the numbers are in.
First, some driving impressions. The car does run smoother and has more power. The car maintains 65 mph on the freeway with less effort than it used to take. Before, I could feel the engine "working" to maintain 65 mph. Now it cruises at 65 and I need to keep an eye on the speedometer.
Now the good stuff. My SL2 averaged 25.75 mpg versus 23.02 mpg for the month prior to installing the E3 spark plugs. I have to admit that because of the increased performance, my foot has been heavier on the gas pedal than normal so the mileage could possibly have been even a little better. All in all, I would say these spark plugs are a worth while purchase that will eventually pay for themselves.
