FWIW I run Autolite AR32's and very happy with them, a 26 sounds to be a very cool running plug.
Autolite has a lookup function, that will cross reference competitors plugs, if you know the competitors part #. Maybe NGK and Champion have similar, although personally I will not use Champion I've had no luck with them in the past.
