E3 Spark Plug E3.68 Automotive Spark Plug, Pack of 1

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 Amazon. 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.

It does fit 2018 GMC Sierra 1500 6.2 L runs excellent

Le quedaron bien al vehículo, y hasta el momento han funcionado bien

No misfires, unsure of life span on them. I'm 13,000km in (often hard useage, drove 12,000km open loop) UPDATE: 30,000km. Still no issues. I cleaned them, they look good as new

Awsome performance
