Product description
Product Description
Autolite Copper Core Spark Plugs deliver quick starts, improved fuel economy, and smooth acceleration. The copper-glass seal bonded insulator, terminal post, and center electrode ensure a tight seal that is 100 percent leak-proof, and the full copper core electrode improves heat transfer and optimizes plug life. Copper Core Spark Plugs feature high alumina ceramic for high dielectric strength, and a steel shell for installation robustness. The multi-rib insulator reduces the danger of “flash over” to prevent misfires, and the copper core center electrode provides higher thermal conductivity. These spark plugs are engineered with a high nickel alloy center and ground electrode for extended life. Autolite has over 100 years of engineering experience and has sold over 11 billion plugs. Since its inception, the Autolite brand has provided the aftermarket and Original Equipment manufacturers the highest quality ignition products. Designed and engineered in the USA.

E3 Power Sports spark plugs are a clear breakthrough in spark plug technology. Developed by researchers from leading engineering universities, E3’s patented electrode design allows for a better spark, and resulting more complete flame kernal and flame front extending off the electrode, producing better overall localized pressure inside your boat, jetski, ATV or snowmobile’s engine’s cylinder(s). This in turn leads to the fuel/air mixture injected into the cylinder being more cleanly consumed, lessening the level of greenhouse gases emitted, increasing energy efficiency and generating more horsepower. .caption { font-family: Verdana, Helvetica neue, Arial, serif; font-size: 10px; font-weight: bold; font-style: italic; } ul.indent { list-style: inside disc; text-indent: -15px; } table.callout { font-family: verdana; font-size: 11px; line-height: 1. 3em; } td.vgoverview { height: 125px; background: #9DC4D8 url(https://images-na.ssl-images-amazon.com/images/G/01/electronics/detail-page/callout-bg.png) repeat-x; border-left: 1px solid #999999; border-right: 1px solid #999999; padding-left: 20px; padding-right: 20px; padding-bottom: 10px; width: 250px; font-family: verdana; font-size: 12px; }

Why You Need E3 Spark Plugs
As the designated catalt for the ignition of fuel in gasoline power sport vehicle engines, spark plugs are a small, but constant factor in the workings of the vast majority of snowmobiles, ATVs, jetskis, boats and vehicles with similar performance needs. What owners of these vehicles may not realize is that their choice of spark plug could play a significant role in reducing the level of greenhouse gases that their engines give off, as well as increasing their overall fuel economy and potential power output. This is where E3 Spark Plug’s DiamondFire technology comes in. DiamondFire Technology
For the last 100 years, the only real advance in consumer spark plug technology has been to develop wato make them cheaper. E3 Spark Plug’s DiamondFire technology changes all of that through an improved electrode design that provides for more efficient burning of your engine’s air/fuel vapor, leading to more pressure in the cylinder. These improvements are measurable, confirmed and based on the following design elements found in existing performance spark plugs. First, the DiamondFire electrode directs the flame kernel to the piston more directly, reducing the travel time from the spark zone to the end gases via the open section at the top of the electrode. Given the short time available to get combustion started, the faster you can get the flame to the piston, the better. Second, the phical features of the electrode project further forward into the combustion chamber. This brings the spark zone closer to areas of probable “good” air/fuel mixture and also creates beneficial “micro-aerodynamics” within the spark zone. The initial combustion wave leaves the spark area at supersonic speeds above Mach 1, and the elevated edge provides a kind of chimney effect so the next round of air/fuel mixture gets into the spark zone more easily. Finally, the E3 electrode design features forced edge-to-edge spark dis, which is the best way to get a spark to leave a surface. This improves upon the phenomena that drove race car drivers to “cut back” ordinary electrode spark plugs in order to improve the spark dis. The spark itself occurs only when an avalanche of electrons migrates from the two electrodes (anode to cathode). Sharp edges are better at initiating electron migrations, and these accelerated electrons collide with matter inside the spark zone to release additional electrons. This design ensures that the whole population of electrons works to create a plasma channel through which the spark current flows more easily, resulting in an increase in both power output and fuel economy, while reducing emissions in gasoline engines and the build up of carbon deposits on engine surfaces.
