Plan on a day of fun! The front three spark plugs are easy to get to; it's those back three. You have remove the black plastic air exchanger(?) on top of the engine. This is not easy. The bolts are in back where you can't see them and you don't have a lot of room to get a socket in there. Once you get that off, then you can get to the back plugs. Again, not easy to see, hard to access, especially number 5. Then, once you finally have the spark plugs changed, you have to put it all back togeth with the bolts going in where you can't see and can't get to very easy. But with enough stubborness, it can be done. Good luck!
