I placed my order a few days ago for some NGK V-Power plugs, but decided to do some reading about the 4.6 after that. From what I gather, this plug is regarded highly but I discovered the dreaded blowout issue that so many people have been experiencing. Now I'm scared that I'll suffer from it as well. It seems that it's happening shortly after a lot of people have replaced their plugs. I've found arguments for and against the use of anti-seize, for and against Motorcraft or other brand plugs, and arguments about a warm engine vs. stone cold engine while changing plugs. In the past, I've never used anti-seize and I've always changed the plugs while the engine was cold or at the most only operating for a couple minutes. I've never used a torque wrench on them... just went by the feel. I take it I should use much more caution this time around. 13lb. ft. seems to be the magic number.

My car is a 2000 GT with 66k miles. I really want to do a tune-up and I've already ordered everything... should I lose sleep over this?

I check my plugs every oil change and sometimes inbetween now that mine has blown out.
Doesn't hurt to check 'em.

If it's as simple as just using a torque wrench, then I'll worry a little less. However, after reading a bunch of threads, I just kind of get the feeling that it's a shot in the dark... some are lucky and some aren't.

Changing the plugs is easy... You can use a torque wrench or not. I havent used one on any of my vehicles... I know how tight the plugs should be... Never had any issues.

I've changed my plugs about 10 times on my stang just cuz i was doing some testing with different kinds. I always make them snug, so when you go to loosen them, you just give them alitte umf to get them loose. That is how my dad taught me and has worked fine on every car i have owned.
Some mustang engines have 4 threads in them for the spark plugs and others have 6 threads so that the plugs hold in better. I think it is the older 4.6's that have 4 threads but i am not certian.
