Review on 🔥 E3 Spark Plugs E3.68 Premium Auto Spark Plug with DiamondFIRE Technology (1 Pack) by John Collins

I heard about this new design a long time ago via YouTube and E3's own website and was curious to try these plugs. As there are no E3 dealers in New Zealand to my knowledge, I am happy to find them through Revain. I used these spark plugs in a Mercedes C180 Compressor 05 OEM equivalent according to the E3 online catalogue. They were just as easy to fit as traditional spark plugs. The design of the electrode does not require gaps. They were significantly cheaper than OEM NGK platinum connectors at a fraction of the cost, even with shipping included. I've driven 2000km on the E3 and they work just like OEM spark plugs. Whether they produce more power or save fuel I can't say, but I'm more than happy that they saved me from having to buy very expensive OEM spark plugs. I hope they continue to perform with the same durability and lifespan and I guess time will tell but so far so good.
