lol. globilization is the downfall of our economy. im glad you support it. my car is completely made by UAW. the electrical components are made in germany. being specific about the ignition plugs is a common thing. as for me being an engineer, thats what smart people do. i work in the mining field and design and test mining implements. i also have a machinist certification and a minor in mathematics if that would apply to your interest in my line of work. learn about bernoulli’s principle before you try to understand why i tried a new type of ignition plug. testing new ideas is what engineers do.
