E3 Spark Plugs

Energy, efficiency, and ecology--that's the E3 equation! The unique patented electrode configuration of the E3 spark plugs increases the amount of combustion pressure created during each power stroke of an engine. This, of course, results in a marked increase in power output, fuel economy, and reduced emissions in all gasoline engines.

NGK Iridium IX Spark Plugs

NGK Iridium IX spark plugs feature an ultra-fine center electrode that's designed just thick enough to ensure the maximum durability and life of the spark plugs—and just thin enough to create an accurate and consistent spark. They represent the ultimate evolution of spark plug technology and performance. Iridium is the hardest metal used in spark plugs today—six times harder than platinum. This allowed NGK engineers to reduce the voltage requirement for a spark. Iridium IX plugs are available in more than a hundred configurations for universal and vehicle-specific applications.

Denso Standard Spark Plugs

Denso standard spark plugs are designed with the smallest details in mind. Case in point: machine-rolled threads to prevent seizing or cross-threading during installation/removal. Each spark plug is 100 percent pre-fired to assure the highest possible quality. The purified alumina powder 5-rib insulator prevents flashover, provides exceptional strength, and significant thermal conductivity. The copper-glass seal cements the center electrode and insulator for a gas-tight bond. Denso standard spark plugs are available with a variety of options—including projected, non-projected, and extended center electrodes, as well as rotary engine versions. Order the model recommended for your specific vehicle and engine size.
