Anyone here running iridium plugs?

[go-stang5.0]

Hey I was wondering what iridium plugs I would need for my AFR 185's. Also, if you use iridium plugs (regardless of your combo) did you guyz notice any difference vs. copper plugs? Also, where can I get o2 sensors cheap? Or would it just be better for me to get them locally?

I'm asking because I'm gonna change my plugs and o2's before I go for the sniffer and while I'm there I was thinking about getting iridium plugs if there worth it. Also, I'm running autolite 3924's right now if this info is useful.

stick with copper for the best performance, if you want to get to get the most out of your combo, play with the gap a lil bit till you find what works best, the platinums will not make more power, prolly less and the only advantage is for some people they last longer, but if you have a modified car i think you should change your plugs every 6 months anyway. iridiums are **** for our cars,,, they are for imports revving to 9k 5.0's dont do that so why bother.

Hey go-stang5.0,

I don't run the plugs but have question on your combinations manners. How is the driveability/gas mileage? I am thinking of the same combo in my 94 gt.
Mine will be daily driver 25 miles oneway, just wondering.
