    NGK R5671A-10 works great and is easy to read and is reasonably priced. If you are really going to push the envelope and want the absolute best then it is the NGK R6061-10 but they are way more expensive. The 6061 has a shorter ground strap that prevents it from turning red hot and acting like a glow plug.
