I had those too, then went with NGK Iridium IV's and have had them ever since.

I just put regular autolite plugs in my '88. Runs just fine. Dont waste your money on bosh triple platinum plugs with 24 karat gold connectors or whatever. Just remember, whatever plugs you get check the gap on all of them.

No need to waste money on fancy, expensive spark plugs. Our 5.0's run best with stock copper plugs. Like the stock Motorcraft plugs or Autolite 25's.

Thank you 302Feen I get sick of all the newest spark plug fads they come out with.

Yep. I've never been a fan of high dollar ignition parts. A spark is a spark.
Take a can of gas... doesn't matter if you use a lighter or a torch. It's still going to catch fire.

Now, when you get up into high horsepower engines, an ignition box is a good idea for a more precise spark, but still no need for fancy spark plugs.

i slightly disagree. i've put in the e3 spark plugs and got quicker throttle responce a more power. E3 plugs are the best plugs. set of e3 plugs, performace wires, cap/rotor and some royal purple will do you car verrrrry good. if you don't belive me on the E3 or royal purple look both up on their websites. i promise you'll think different. =] GL though on whatever your choose.

Don't believe anything you read about a product from the company who makes it.. If everyone gave an accurate representation of their product, Obama might have been a good president . Fact is, just like Obama, fancy spark plugs aren't going to do any of the crap they claim any better than another plug. I went with the NGKs over the Bosch blahblahblahs cause one of the Bosch plugs cracked way too easily and the NGKs seemed popular amongst racers. I didn't notice any performance difference between the two, though. If you felt a difference when you put those e3 plugs in, how old were your old plugs and are you sure the gap was set right? Thats where the real difference comes in

Agreed!
Here's how I see it:
In any internal combustion engine it takes compression then something to ignite the compressed air/fuel to create power.
Put the right air/fuel mixture under enough compression and it won't matter if you light it with a small spark or a lighter. It's still going to explode! That's all you're looking for.

NOW, when it comes to higher HP motors and cars with blowers/turbos and/or N2O might need an aftermarket ignition box to provide a more precise spark to each plug. But your still only looking for that spark to ignite the compressed air/fuel.

Think about a Diesle. Most don't even use any kind of spark plug. They simply run enough compression to ignite the air/fuel by itself.

I wasn't willing to pay out $50+ for a set of E3's on my last tune up, so I went with plain old Motorsport copper plugs. That's all you need.

Though, Horsepower TV did an engine dyno comparison of copper vs. E3 and E3 came out with a few more HP and slightly better fuel economy. Take it with a grain of salt, since they're a sponsor of the show.

im using e3 plugs right now, and to tell the truth, i didnt notice anything different from the autolites or ngks in mpg or hp.. but i still chose the e3's because they were a bit cheaper than the ngk iridiums and was told they would last longer than the original copper? dont know if its true, but what the heck.. ill give anything a try atleast once.. well, maybe.. lol

Guess I'll ask the question here. What about if you have GT-40 heads? Not since I swapped out the stock heads for them like a year ago have I changed them out. Are they the same or what? And do they get the same gap as stock?

I'm pretty sure the GT40/Cobra heads use the same plugs as the GT's. I would double check that though just to be sure...

After buying my car in 2001 i replaced the factory (as in original with over 100k) copper plugs with motorcraft or autolite platinums and never had a problem since.

The original plugs in our cars had white paint on the wire end and the electrodes were sunk up into the porsaline...lol Needless to say it ran better but i am planning on switching back to autolite coppers just to see what happens.
