    either reach back there and get at them or UNBOLT the two DOG BONES (engine mounts) the are directly in front of the motor, trust me you will know what im talking about. after you did the, get a rachet strap and pull the motor foward buy hooking the one end on the engine pull bracket in the back and hook the other hook some where on the front, by the motor mounts to give yourself another 3-5 inches of space to get at them.

    Step one. Remove all the usless brackets. Step two change rear plugs. One you clear all the crap you will find plenty of room

    lay over the passenger side fender on to the engine, your left hand will be able to get back there with no problem. the boots are gonna be the hard part of the process

    but seriously, 3/8s ratchet, 3" extension, 5/8's spark plug socket and you win.

    Those exhaust manifold heat shields are SHARP! Seriously!

    One of the edges went thru my finger like butter when I was changing my rear plugs.

    Overall our engines/cars are easy to work on. Reach on back and do whatever it takes to get them out.

    The tools I use: Wrench, joint socket, socket.

    It seems to take the same amount of time to reach back and squeeze in as it does to unbolt and bolt the dogbones and strap the engine forward.

    Definately get a joint socket or a joint extension.... i find #6 plug is obstructed by the 02 sensor... so its go around it or pull the sensor to replace the plug.... such a pain those back 3, but you can do it

    Do what I do and go buy a case of beer and call a broke ass friend who wants to drink to come throw back some beers and turn some wrenchs. That way you got a a drinking and wrenching buddy for the night. Saves on all the cuts on hand from heat shield

    The easiest and simplest way to remove the rear plugs is to first remove the acoustic plastic engine cover steel bracket at the rear of the engine The two nuts are 13mm. To remove the #6 plug remove the O2 sensor with a 7/8" special socket. This will give you clear access to the plug since the sensor sits almost in front of the plug. When the plug is installed install the sensor back but be sure to coat the threads with thread sealant. Also, when installing new plugs put a thin film of dielectric grease on the porclin and a thin coating of anti-seize on the threads. This will allow easy plug and wire boot removal at the next removal. Exercisr these steps and the process will prove much easier.
