Corvettes Achieve Peak Performance from E3 Spark Plugs with DiamondFire Technology

Keeping a Corvette at its peak is expensive, which is why even the simplest things are important. Something as easy as changing out your spark plugs can deliver maximum results when it comes to performance of your prized ‘Vette.  E3® Spark Plugs with DiamondFire™ Technology  deliver  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 Corvette will have the performance it deserves.

Lasting engine performance isn’t the only thing you will notice when you switch to E3 Spark Plugs. Just by switching your plugs, there is a noticeable reduction in carbon buildup in the cylinder and on the piston head, which leads to longer engine life. Research shows that emissions are also reduced.

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