You can ck with your local part store or the dealer. last time I ck the wire set wasn't cheap. If you are replacing the spark plugs. Here is some advise, remove the inner fender lining, they are bolted on 8mm or 5/16 sockets and the tires too. replace the spark plugs thru the fender not on top. takes me 1 1/2 hours this way instead of 3 to 4 hours for 16 plugs.
