Designed for durability, it offers a 5-year/100,000 mile warranty and significantly reduces harmful emissions. Compatible with motorcycles and select vehicles, it requires no gapping and delivers a reliable, cost-effective upgrade over OEM plugs. ## Description E3 has taken the best features from traditional spark plugs, such as cut-back ground electrodes and surface gaps, and combined them to create a new ground electrode design. Surface gap plugs present the flame kernel to the piston (or rotor) more directly, reducing the travel time from the spark to the combustion gases (although this difference is only measurable in hundred-thousands of a second, at 5000 RPM, they can add up). This avoids the "doughnut" shaped flame front created by standard spark plug electrodes. This is achieved in the E3 design through the open section at the top of the ground electrode. E3 spark plugs combine the benefits of additional sharp electrode edges with a cut-back electrode design used on some racing spark plugs. The increase of available edge-to-edge surface area encourages a more rapid spark discharge while also reducing quenching and shadowing. The two legs that support the special geometryof E3's powersports plug ground electrode aid in heat dissipation for longer electrode life. The center electrode on E3 spark plugs is created from nickel alloy with a copper center core for both improved conductivity as well as heat dissipation. Review: I haven been aware of this new design for some time now through YouTube and E3's own website and have been curious about using these plugs. Since there are no E3 retailers in New Zealand that I'm aware of, I'm glad to find them through desertcart. I used these plugs in a 05 Mercedes C180 Kompressor as a OEM equivalent as per E3's online catalog. They were as simple to install as regular spark plugs. No gapping required with the electrode design. They were significantly cheaper than the OEM NGK platinum plugs at only a fraction of the cost, even when i include shipping. I've driven for 2,000kms on the E3's now and they perform just like the OEM plugs. Whether they produce more power or save fuel I cannot be certain but I'm more than satisfied that they saved me the purchase price of the very expensive OEM plugs. I hope they will continue to perform with a similar durability and service life and I guess with that time will tell but so far so good.
