I am trying to assist someone with some research on a racing mzr and I had a quick question for you duratec folks.
Do your spark plugs have tapered seats or washers?
Also, what plugs do you prefer? He has had good success with denso iridium racing in the past, but it seems only denso iridium power are available for the mzr.
