E3 Spark Plugs with DiamondFire Technology Delivers Optimal Performance

With so many performance-enhancing upgrades on the market, it’s hard to decide what your car really needs. Sometimes the simplest act, like changing your car’s spark plugs, can increase the overall performance of your vehicle. E3® Spark Plugs with DiamondFire™ Technology delivers the most powerful spark available on the market, leaving a lasting impression in your engine. The unique geometry of the E3 design provides optimized spark paths well into the useful life of the spark plug, having long-term effects on engine performance.

Only E3 spark plugs feature a diamond-shaped electrode with a revolutionary Edge-to-Edge design. This patented design, the result of years and years of independent testing, delivers forced edge-to-edge spark discharges; proven to be the most efficient and effective way to get a spark to leave a surface. DiamondFIRE technology, proprietary to E3 Spark Plugs, allows the fastest flame-front to grow unimpeded towards the piston to create a more complete burn of the fuel/air mixture in the cylinder. By simply replacing your existing plugs with premium E3 spark plugs, your ride will have the performance it deserves. Horsepower gains of 4-6% can be expected, depending on engine class size.

Backed by a five year, 100,000 mile warranty, E3 automotive plugs with this remarkable DiamondFIRE technology are now available for most vehicles at automotive retail stores nationwide.  For more information and complete test results, visit www.e3sparkplugs.com.
