You have to remove the air intake duct from the fuel injection system and move it out of the way. It's not easy, you just have to squeeze in there and try to reach them best you can. It may help if you put the front of the car on ramps or jackstands and reach in from the bottom. Good light helps too. It took me an hour for the whole job the first time i did it. It is best to get the good spark plugs that last longer. Good luck.
