Sparkplugs/removal
First - I am a geezer with a 1993 5.0 LX CV I bought for my second childhood - a stock, low mileage car. The shop manual says to change plugs every 30,000 miles. I am at 61000, don't know if they have ever been changed. Past posts show the Autolite 25 to be a standard plug. Is this correct? Any trickery required to remove the plugs? I am more used to working on the 289's in the early Mustangs.
Is there a danger in stripping the threads removing the plugs? A section in the shop manual covers removing the head and tapping the plug threads.
I know this is elementary for most of you but I would appreciate the info. Thanks

I changed out the sparkplugs in my 92 GT 5.0 convertible with no idea what I was doing. I found it easier to do it one at a time so I wouldn't get any wires switched up or get lost. Not sure about the Auto-lite 25's. I decided since I had a 5.0 GT it would be better to spend a little extra just in case. I ended up getting Bosch Platinum Plus 4's. My car seemed extremely happy to get them. As far as stripping the threads goes, I used a magnetic 5/8 socket and gently took my time getting them out. When I put in the new ones I put them in by hand and then tightened with the socket the rest of the way.
Hope this helps..

Holy **** dude i was just trying to convey that he has already done this job before on the older 289. If a person has changed plugs on a 289 he has changed plugs on a 5.0
