I don't think you can return INSTALLED/USED plugs...I hope you haven't yet.....but maybe they'll be kind to you...and this...
Why do you always ask for advice AFTER you do something?...AFTER you buy oil and fill the crankcase....AFTER you buy cooland and attempt a drain/fill....AFTER you buy/install spark plugs...
The advice you got here is the same as you got on ToyotaNation...that you should be getting professional advice, and not from some over-the-counter-jockey...
...and that the best thing you can do is to stick to OEM specified parts...advice you seem to have chosen to ignore, looking for "something better" ... more of this, more of that, le$$ of thi$, less of that...and in the end it always seems to cost you more, as in the case of plugs that must be replaced sooner...and possibly cause more damage than if you just stuck to basics...
