ngk coppers is all I would use. No plug is going to make that much of a difference.

True but when you think about it everything they say makes 99.99% sense.

And imagine if you were to indexed these plugs. Maybe more than a 1-3hp gain

prepare to get a new coil or upgrade to a MSD coil.....just my experience with "more powerful spark"


Here’s how it works: Electrical energy from the engine’s power coil


need i go farther.....LOL for some reason it kills older coils.....i would say before their time.....

ive read a couple of reviews on them already. They dont seem to work on ALOT of cars and seems to actually be worst than old plugs. Some cars that used them ahve failed after a month of use. There seems to be a lot of horror stories with these. I say try at your own risk, but they seem to be an expensive risk.

If the car is made in Japan...then it's nothing but NGK or Denso for me. Copper, Platinum, Iridium - take your pick.

I use NGK copper...cheap enough to change them every 25-30K and just keep truckin'

As said earlier i think cars fail after a month due to the coil not being able to take the charge or something. And if these must be used succesfully a MSD coil may be needed. And it is an expensive risk
