E3 Spark Plugs
With today's gas prices, it is now more important than ever to keep your engine running efficiently. Before you hit the road, check the plugs. You could easily be down on power because of a few faulty plugs and you may want to swap them out for a set of E3 spark plugs with DiamondFire Technology. They feature a diamond-shaped electrode with a revolutionary edge-to-edge design. This patented design is the result of years and years of independent testing, and they claim it delivers forced edge-to-edge spark discharges. The plugs are backed by a five year, 100,000-mile warranty.
