DiamondFire technology, proprietary to E3 Spark Plugs, allows the flame-front to grow unimpeded toward the piston faster to create a more
complete burn of the fuel/air mixture in the cylinder thus increasing power and reducing the amount of fuel/air mixture that is vented out through your
exhaust. By simply replacing your existing plugs with premium E3 Spark Plugs, your engine will have improved performance and efficiency. Backed by
a five-year, 100,000-mile warranty, E3 Spark Plugs, with its remarkable DiamondFire technology, are now available for most vehicles at automotive
retail stores nationwide.
