Which type or type of sparkplug should I use in my 1980 Puch Maxi?
go with Bosch Platinum or Champion, there is a plug reference guide in the "resources" section at this site, check the proper application on the Maxi, or do a cross reference on the plug you have now.
Bosch W 7A ( W 175 T 1 ) or a Champion L86. Hint ...it's the same plug a VW beetle uses.
