    As long as I've owned a vehicle, the spark plugs have been NGK. I will not settle for less. I've got the Iridium IX in my 91 Miata and along with the Magnecor KV-85 plug cables, I could tell a difference in the first time I fired it up and went for a drive. Smoother overall engine performance, definitely, especially under acceleration load.
