If you are not in the automotive industry, you might not have heard of this company. They make spark plugs and oxygen sensors. The stuff that you motor needs in order for it to work. Without these spark plugs, you car will not be about to move. Anyone with is remotely interested in the automotive industry should understand how important spark plugs are. But then most people don't even care what goes under the hood right? I mean as long as the vehicles moves, we don't really care. However, spark plugs is a very important part in the operation of the vehicle. We should all take note. Anyway NGK makes one of the better ones in the industry. They started in Japan (where else?) and the US subsidiary began operations in 1966. They have been supplying spark plugs to the industry for more than 35 years and still going strong.Other than spark plugs, they also manufactur oxygen sensors, wire sets and performance accessories like spark plugs for racing cars (or high end cars), splicers, air-fuel monitors and so on.
