22's or 32's
will autolite ar103's work fine as a replacement plug for a stock pully cobra, if no any suggestions.
i had my car on the dyno last week and the tuner suggested ar103's for a stock cobra
i read somewhere that the 103's were 1 heat range colder then stock plugs, but what plug 12, 22, or 32.
