Hey, sorry for the late reply. If you want the Iridium IX go with the LFR7AIX (not -11). They are one step colder and have the same gap as the stock plugs. The LFR6AIX-11 have a larger gap of 0.044 and you have to gap them at your own risk (if you are brave NGK does not suggest you do that though). If you want the stock plugs that come in the 05 GT from the factory, the number is SILFR6A Subaru #22401AA670 Stock #7913. They have the exact same construction as the Iridium IX, tapered ends and Iridium center. However they have the proper gap of ~0.028-0.030 (I was not able to fit in my 0.030 feeler but 0.028 went in... I did not want to force it). I got my plugs from Jeremy at FredBeansParts.com, I originally ordered the wrong ones and quickly caught it, as the gaps were different. Jeremy was really helpful to me and exchanged them for me. Not to mention free shipping. I was really happy about it as I was pulling my hair about making the wrong choice and screwing things. Two thumbs up for Jeremy, he saved the day with flying colors Summary: 05 GT: Stock: NGK SILFR6A Subaru #22401AA670 Stock #7913 One step colder: NGK LFR7AIX (not -11, if it has -11 it's the wrong gap) Stock heat, bigger gap: LFR6AIX-11 (This should work on the 2.5i w/o regapping ) It will work in the GT but I do not wana risk it and went with stock. and Did I mention Jeremy at FredBeans rocks!?

I took mine out last week. The hardest ones to get out were the driver side ones. I broke both while trying to get them out, lucky it was the old ones. http://farm4.static.flickr.com/3158/3330974283_49d128c44d_m.jpghttp://farm4.static.flickr.com/3390/3331809286_1a6f2964e5_m.jpghttp://farm4.static.flickr.com/3654/3331810348_fbc15644ea_m.jpg click to enlarge (these are not the IX that went in)
