I bought these spark plugs with a little reluctance. Is this a "typical" marketing gimmick? My Toyota Echo has 175K miles and averages about 36 mpg, with an automatic. After reading about the Pulstar plugs, I thought I would take the chance and make the $40+ dollar investement. It has been just over a week since I put them in, and I have noticed a smoother idle, a little more pick up, and my first fill up since installation showed 38 mpg.
