Go with the stock irridium plugs if your car is not modified. I am not famillar with that type of part number for the irridium so go to a parts store that carries irridium plugs (such as auto zone) and compare numbers on the plug with the irridium stock plugs they show you. They will also have a catolog that will show the heat ranges of the irridum plug if you ask to see it. If you are not running alot of high performance I would recomend ditching the denso irridium and getting standard denso's in the stock heat range.
