You match the plugs with pictures. Also, most are ac and smaller than the dc in physical size. Good dealers will put measurements of cdi in the ad. My 150 I determined was ac, as most are, and I upgraded to one with no rev limiter. I can tell a big difference in take off and at least 5 mph on top end. Still need to check it with gps. Cost me 10 bux.
