Tip & How-To about 1999 Mercury Grand Marquis

Spark Plug gap & torque

The Motorcraft AWsF-32P plug is designed for this 4.6lit engine
The gap should be set at 0.054 inch.
The torque of the plug should be between (84 to 180 in.lbs.)
anti seize lube should be put on plugs threads before instillation.
Some of the plugs are hard to get to, however if you cut 12 to 16" rubber hose & slide over the plug, it makes the job alot simpler. Hope this helps.
