Changing the spark plugs at 100,00 is good in theory, (right up there with oil change extending fluid[not]), but if you busy twisting yourself in yoga positions to work on something else under the hood , do yourself a favor and make the change before 100k. It made my car run better with the change at 75,000. I replaced them all without to much trouble. The plug that found itself a bit more resistant was the left far corner.. after the air box and battery was out ,,, it was possible to get it out by using a board to lift the enging a bit off the engine mounts to get enough room to work the plug out.
