Review on 🔌 E3 Spark Plugs E3.64 Automotive Spark Plug, Single Pack by Caleb Quade

We have 2 BMWs (650i and 330ci) and 1 Audi (A6) in the household and I have E3 installed in all. First of all, I would like to say that E3 should expand its marketing to German-made cars. My BMW dealer and other dedicated BMW repair centers have never heard of them and warned me not to fit anything other than the manufacturer recommended OEM replacement spark plugs as I would most likely cause the engine to misfire or at least check the check engine light for problems with the state have supervisory authority. None of that happened. In fact, all three machines have never performed better. They have more power and better mileage. I would recommend E3 to anyone asking for it.
