Purchased for a 1974 mx250 Yamaha.With the mass confusion with part # supersessions I went to ngk sight to order correct plug (from Jeff of course). Specifications clearly say removable cap which most dirt bikes with a 3/4 reach plug utilize.Cap is non removable . I’ve emailed ngk but no response as of yet.

Use these spark plugs in my 2 cycle powered aircraft and would not use any others, have monitored iridium spark plugs since there conception in the auto industry and feel they are the best and most durable, less chance of fouling.

Only speak plug I trust now. I can do 4 day rides on one plug with out fouling. With regular plug I'd be lucky to make it through 2 rides.

Work well in every way a spark plug should and if other plugs are any indication, and they should be, they should last a long time.
