I drove it around for a little while, it wasn't what I guess I was expecting, but it is better than the Bosch Plats I had in her. You are right txfo, a smoother idle, but if I get the 8mm wires I imagine they will help get better performance. Vato Zone sells them for $28.99 for the spi. Well maybe next month...

put Iridiums in my car too. they last an extremely long time. youre not ever ever ever going to see huge noticable gains in power form just adding spark plugs. most plugs on the market are hyped by marketing and do nothing special whatsoever.

benefit of iridium plugs: long life, smoother idle, more efficient fuel burn, increased gas mileage(i gained 4-7mpg additional over Motorcraft plugs).

they wont run hot unless you put in spark plugs of the incorrect heat range.

there is only one downside to them, the price.

I'll let you all know how they turn out for me, I have a fresh oil change, and a new air filter too. I do a lot of commuting from leavenworth to kansas city about 35-40 miles, 4 to 5 times a week. so I should see something happen as far as the fuel mileage goes...
