Automotive Spark Plugs

Simply stated, E3 spark plugs were "Born to Burn".

When it is time to buy automotive spark plugs for your car, choose E3 spark plugs with their patented DiamondFIRE ground electrode. E3 automotive plugs were designed to burn fuel more efficiently by burning fuel more completely. Most plugs create a flame shape that moves sideways from the central electrode. Our flame kernel moves toward your engine's inbound air/fuel mixture. This creates a higher combustion pressure for an improved burn time that minimizes the waste of unburned fuel.

So the next time you buy automotive plugs for your vehicle, remember our spark plugs will provide a like-new performance for the life of the plug. After years of independent testing in conjunction with researchers from leading universities, we decided to ditch the standard "J-wire" electrode in favor of an edge-to-edge design. Since the diamond-shape electrode architecture produces a larger flame, much of the leftover air/fuel mixture is burned rather than passed through the engine's exhaust. The most environmentally-friendly plug available at a price you can afford.
