not sure which all plugs PG have listed on their site, but he denso's you want are the ITV22's. they are one step closer than stock and are way closer to the proper gap than the NGKs.

your telling me about the gap? lol. dude seriously...after modding a bunch and trying to tune the car my plugs are throwing random misfires up the a-hole. i need new plugs bad....ones that actually work right.
Wow! The OP asks for help, someone steps up and volunteers to help with the exact info asked for, with the right Denso plug number for one step colder, even tells him that they are gapped correctly (we have to regap the NGK's I prefer) and the OP slams him?
What more can the OP want? Frustration over the situation is understandable. Lashing out at someone trying to help? Let no good deed go unpunished.

i did slam him at all. i was just saying the phrase...."your telling me" like...yea i know...they aren't even close. sorry if it came out that negative. no harm meant.

That's cool. So what plugs did you go with and why? Did they solve your problem?

i switched to the denso's intead of the ngk's because theyre closer to the gap the car needs. the ngk's with my tune give me crazy misfires at WOT and 18-19 psi. i thought it was the fuel at first but when i checked the fuel pressure it was only dipping to like 1400 psi which wouldnt make a big difference like i was feeling. the stutters would throw a random misfire code and i would revert to the stock map because i literally couldnt run the aftermarket map. hopefully the denso's will fix this problem. **fingers crossed**

lol?
Sort of tongue in cheek. But, for those not familiar with the wire gauge tool and how to carefully bend the ground electrode, the center electrode can be easily damaged. For those with just a little bit of experience -- a piece of cake.
Hate to see someone throw away a good set of plugs that could have been re-gapped to proper specs.

well...i needed new plugs so i went with the denso's. should have gave you the whole scoop i guess. but then again....NONE OF YOUR BUSINESS!!!! lol. jk. these plugs have been in there for 45,000 miles, much beatings, and in buying new plugs i went with denso's so i dont have to touch them. i have the knowledge to re-gap them. i just decided i should buy new plugs.
i doing my religious 50,000 mile treatment. replacing the spark plugs, put in some new redline tranny fluid, new cp-e air filter, ran sea foam through the system, put on new sneakers, blah blah blah...
do everything at once so i know it all got done at 50k. easier to remember and i know its all done.
Now it makes sense -- I guess I was a bit dense on your situation. If you got 45K miles on that set, then it was time to get them out of there.
I don't think there's a dime's worth of difference in performance between the Denso Iridium and the NGK Iridium IX in the same heat range. It's just that the NGK's in Range 7 do have to be regapped as they come at .045 or so - huge gap.

seriously....huge gap. what is our car modified with a custom map? you should be running like a .26 or .28. lol.
A gap of .030 works best for me with my mods and on stock tune.
For those with dyno dollars and time, you can adjust up as much as .008 or down as much as .008 (.002 at a time) outside the factory specified gap range and find the sweet spot, which could be worth as much as 5 whp, and this will vary from engine to engine, even with the same mods, for some reason.
With turbo engines, increase in boost over stock levels (custom map ??) will usually produce more power by narrowing the gap.

"custom map" increased boost, fuel, yada yada. pretty much mod specific tune.
cool thanks for the info. ill use that when i get my new plugs.
