        Those "Surface Gap" plugs (some people call 'em "side gap", some 
        call 'em "360 degree plugs") are used, as far as I know, ONLY on 
        2 cycle, outboard type boats. That explains why YOU had 'em. :-D 
        Anyway, they're supposedly /real/ resistant to fouling out, so 
        that's why they use 'em on those motors.. I suppose they use 'em 
        in that application only is because they figure the boats will 
        be out in the outdoors, abused and neglected more than the 
        average vehicle. You know.. stale gas and whatnot. 
        
        Anyway, they DON'T use 'em on "normal" cars, because the gap 
        can't be adjusted on them. You figure, if they outside of the 
        plug is the "prong" side on the regular plugs.. well, you can't 
        MOVE the outside of the plugs inwards, so you just can't gap the 
        things.
        
        I dunno what else to tell you.. they're spark plugs just like 
        anything else, ceptin' someone lopped off the little prong-end.
