Denso Iridium Power spark plugs

Well. Changed out my oem NGK plugs for the Densos a couple days ago. I have to say, Im very impressed. The difference in power and gas mileage are both very noticeable. Two tanks of gas on the new plugs so far, and my average has improved from 16.1 to 19.3 so far. Working on the third tank now and its looking just as nice on the guage. The added power isnt remarkable, but is noticeable. I have a pretty heavy foot, so it has gotten a bit of testing. Also, after a complication with my order on the plugs from sparkplugauto.com, ive built a repertoire with the owner of the company, and he offered that if I need anything at all from him, contact him directly and he will "hook me up". The website price is 7.79 per plug I believe, which is already a great deal. So if anyone wants to try the Densos out, let me know and we will take advantage of his offer.

Alright so I went from 18hwy to 15.3hwy and all I did was change the plugs and do an oil change to royal purple w/ a Mobil1 filter. Oil looks great and is at the correct level still. I think Im pointing the finger at the NGK Iridiums.

What gap is everyone using on your iridiums? Maybe mine is off....

Stay with Denso or NGK to be safe.

I always use Denso iridiums on all my vehicles.

Did you get a discount or pay the going price listed on the website?

I just shot an email to the owner of the site asking how much on the plugs just now since AJ wants some too. They messed up with my order pretty bad, so to compensate, he said on my next order he wants me to communicate straight to him and he will hook me up.
