E3 Spark Plug E3.52

Want to unlock more power from your engine and actually burn less gas? Through an intensive R&D process, E3 has created a spectacular new spark plug that creates the industry's fastest spark growth and fastest combustion pressure rise, meaning it burns fuel more efficiently to give you more power and increased fuel economy.

E3's patented design forces the spark discharge from one sharpened edge to another, and projects the spark forward into the combustion chamber, unlike traditional spark pl ugs, for the most consistent, powerful and efficient burn possible!
