Now you don't have to think about whether you have bought the wrong spark plug, if the engine is original and not replaced, then this is the plug you should have for your car. When you install the new spark plugs. Start by blowing away the dirt around the old ones, Check and possibly adjust the distance on the new ones. It should be 0.9mm, put a drop of oil on the threads before you mount them. Don't pull too hard, as usual, just enough is best.
