Just boufht these plugs and installed 4 days ago. I have to say, theyre worth the $$ so far. Noticeable power increase, and best of all, mpg went feom 15-16 to 19.2 on 2 full tanks so far. Mostly stock 07 4wd.
Got em pretty cheap at sparkplugauto.com. I think $8 each or so

Did you happen to measure the gap on the old plugs after you removed them?
