Iridium plugs? anyone running them?

[boostingbuick]

I was just wondering who is running these and if you are a high hp car. I was going to buy some denzo's but not sure if they will cause detonation like platinum. Autolite also makes a set but not sure about those. Thanks.

Run the NGK iriduim vx in my harleys and it was a drastic improvement.

I just run the plain NGK's in the GN and they run the exact same as the autolites and ac delcos. No difference to me I run 1 heat range cold

I have tried the other platinum, etc and no difference save the money and get alky

I have not tried them but for the price I don't believe the hype.

But they won't foul as easy and should not blow out like standard plugs. I know they run them in a mustang class with power adders. Just wanted to make sure they won't cause it to knock.

I ran them in my LS1 camaro and absolutely HATED them. At first, they were great... but after about 3K miles, they were GARBAGE and the car wasnt as fast and didnt run as good with them in there. I say the hell with Iridium plugs.
