NGK 5306 is a good plug to use . You don't need these exotic platinum or iridium plugs . Your plug gap should be .044 .

Most of the technicians I deal with recommend putting the OE Champion plugs back in them. I haven't been a Champion plug fan, but if the dealer and independent shops are both recommending the same thing, i'm sold. Plus they were alot more reasonable priced than some of the plugs I was looking at.
