I used the copper anti-sieze on the plug threads, its rated to 1800f on the temperature. Torque the plugs to 13 ft lbs (156 in lbs) to get the proper seal. Don't torque cold plugs into a hot (warm) engine. If the engine is hot, the plugs will be overtight when the temps are equal, and will be a booger when it comes time remove them next time. Install the spark plug ends of the wires first, then the coil end. When you first remove the wires, twist the boot about 90 degrees as you pull it off. On the GT, there is a plastic cover over the throttle cables, it comes off with a clip, you'll need to remove this to get access to spark plug #3.
