Excellent, if unusual, plug for a classic British Sports Car
Car runs wonderfully with these. This is my second set. It's unusual to have a Platinum plug recommended for a '70 Triumph GT6, but they work great. Even more unusual is the recommended gap setting of .040". I have an upgraded ignition system, so a gap that wide should be easily handled (probably even wider), but I think these plugs, even with that gap, would still work very well in an unmodified engine.
