what plug gap should I run with Iridium plugs?

 

run the gap that they came with. they come pre-gapped for a reason. which ones you need depends on set up.

 

If you do decide to gap'em be VERY Careful on the electrodes

 

Thanks for the feed back. I checked the gap on the plugs they are at .051-.052 out of the box. so I'll install them with this gap. it seems a bit big but I have never used this type of plug before.

 

what plugs did you get (brand and numer) and what are your mods

 

^^^ YUP...

 

the spark plugs are Autolite XP Iridium .6mm finewire part # XP5263. ( the advance auto parts in middletown did not stock denso,or NGK.) The SRT-4 is an 05 with 6,000 miles and is bone stock. ( its my wifes car thats why there are no mods yet, but she will give in sooner or later.) The only reason I changed the plugs, is the car would skip or stumble on a cold start and if you put your foot into it at nomal speeds. It did not do this all the time . When I pulled the stock plugs they looked like new, no color on them (lean?) Thanks.

 

i havent heard of anyone using Autolite on their SRT. So i cant reply to how it benifits performance wise. Many pple here uses NGK, Densos, & some still have the factory still install (RR you still have yours). Their are websites, which you already may know, that you can order from. Maybe some has a set and they can better give ya some input.

i haven't even heard that autolite made a plug that could fit the srt. are you sure that they are the correct plug? ones for a regular neon will not work in an srt.

 

the plugs were the same thred length and over all length was the same. I have no way of cross refernceing the heat range. they are in the car now. it seems to run good. so I'll keep you posted If I run into a problem with them. The guy at advance auto said there is a 5 year warranty unlimited milage. so if there is a problem I'll return them.
