NGK's seem to work very well in our cars but I also have an iridium plug called the WeaponX that is a little less than an NGK iridium and produces good results as well.

I sell 50 TR55's to 1 TR55IX, I also carry the E3 as well as most of the other brands but the NGK is by far the most popular. With heat ranges from 5 to 10 in a reasonable price. The TR7 (BR7EF) is popular with bigger cube hi hp cars and power adders
