I just called the local Mazda dealer and ordered a set of spark plugs for my 88 n/a vert.
He checked into availability and said he was getting the last set in Canada and they were discontinued.
What is an alternative to the special NGK RX7 spark plugs I've been using?

Buy them from a local parts store, or on line e.g. Rock Auto.

 

i get mine from Napa. i order a set every year

 

Thanks, I'll try NAPA
