ND Spark Plugs for Honda 550
« on: May 30, 2013, 07:33:42 PM »
Pulled these out of a motor I'm working on

I think ND became just Denso a while back - anybody know about how old the plugs might be and if they were special purpose ?

Thanks

Are you wondering if they are collector spark plugs?  :)

not collector really, I just thought that the brannding had changed, I'm guessing these are a few years old
