Denso Iridium plugs?

Has anyone had any experiences with these types of spark plugs. I'm switching mine out on 96GA and they have these available here for about 12$ each, just wondering if they're worth the extra $$

i have never used them, but you might want to try them. but if you dont get those just get there regular AC delco plugs that came in the car

I agree with grandamld9 , the delco's are fine unless you got some mods on the engine and even then they work good.
