im not shure which plug is best for your car.....weather is a factor in choosing from a hot to cold plug......some motors just like a certain plug type or temp......the numbers listed 1/2/3...etc represent different temperature plugs....the motor is a standard so you will want some type of standard plug.....your manual should sugest one or do a search on here or the net for info on your specific car......
if you look at this page....at the bottom it lists what products people bought that bought your motor, there is a os #8(medium) and a os A3(hot)...listed, there is a good chance these would work fine.......
