When I was ready to install the new plugs, I stuck the old plug on the end of a foot long piece of rubber fuel line, then dabbed some anti seize on the threads and ran it down into the plug port as far as I could until I felt resistance. Then I removed it, cleaned the threads, dabbed a bit more anti seize on it, and repeated. I did this until I could run it all the way down without resistance. Then I dabbed the new plugs and installed. You dont want to screw up these aluminum heads!
Other than this tip, I essentially followed the instructions on the Bullitt Registry as someone noted above. Easy stuff, but take your time.
Duct tape is more common than a telescoping magnet.
And maybe your car is different but over that plug nearest the passenger fire wall (plug #4?) I have at least five hoses and harnesses. Some can't be removed or disconnected, hence a simple swivel will help tremdously. This is just from my experience.
And be sure to suck out the debris from the holes BEFORE removing the plugs.
One more thing... torque 7 - 14 ft/lbs and no more. I think that's about hand tight and then a 1/4 turn.
Lol yea, but that little magnet is freakin awesome. Its as short as like 4", then extends to around 2 feet or a little more.
It may be different on pre-99 4.6's, but I was able to stick the extension through the jungle of hoses straight to the plug well. Re-installing I just dropped the plug down in the well and spun it with the extension by finger, then tightened it up.
