How do you change spark plugs on a 1994 Lexus ES 300?

I am a Ford Mechanic and I happen to own a 94 Lexus ES300, and your not going to like this....to get to the three plugs in the back you have to put a jack up the car, put jack stands under the front of the car, then you take the jack put a piece of wood on it so you dont damage the oil pan, raise the jack under the engine just enough to take the pressure off the engine mounts. Then you have to unbolt and remove the engine mounts, then lower the jack. now the engine will be low enough so you can access the rear plugs. RECOMENDATION...If I were you sence changing the plugs on this car is such a pain I would spend a few extra dollars and get the pre-gapped Bosch Platinum 4 prong spark plugs, they last the life of the vehicle and never have to be re-gapped. This way as painfull as changing them is, you will NEVER have to do it again.-Sean All you need it a Flexable adapter that can connects to your extention and you can add extentions and reach them from the top.. Still not easy but reachable. Regards.
