I don't know why, my tuner runs them in alot of customer cars, I change my plugs every year once winter clears up, ran NGK once and there was no difference.

well sounds like i will just be getting some motorcraft plugs then. I've usually always stayed stock anyway. my other cars Ford Probe Gts i've always used ngk cause that whay came from the factory. i was never a fan of champion plugs hell i wont even run them in my lawn mower anymore lol. I knew the E3 wouldnt make much if any extra hp but wasnt sure if it would be better for them motor once i start mod it especially with ignition upgrades.

Ngk copper here. Copper doesn't bother me. They're cheap and i change them pretty often due to citrus tuning.

They are NOT "copper" plugs, they plain ol' are nickel-chrome electrode conventional spark plugs with a copper core--the same as those made by most plug manufacturers.

There is nothing special about them, that's why they are cheap...

So they're the same as most others and cheap. Sounds good to me!

To clarify, they are the same as other maker's conventional cheap nickel-chrome electrode 30k mile maximum--without reshaping/regapping the electrodes (which BTW alters the heat range)--plugs.

Way out of class as compared to any platinum plug which will perform as nearly new for 75k+, "last" to 100k, and only cost $1 or so more.
