I've been following this thread from the start. Just biting my lip.
But I can't hold back any longer!
You can get name brand, no wait, Top quality NGK plugs for ONLY 7 Bucks! And your complaining about the price!
WOW!
I pay 20 bucks a piece for standard NGK's, A set of 4 plugs for my Mazda top 200 bucks!
I can only dream of quality spark plugs with such a low price.

BTW: just to confirm what the head supplier said. You can call NGK, give them all your info and see what they recommend. Their tech support is very good IMO.
At least if you look at the plugs and think you may need another heat range, you will have their recommendation.

I used to have a ridgline and one of the guys on that forum bought plugs on amazon and one had the electrode explode damaging his engine... Well he found they were fakes and not properly built at all making them likely to explode. theres lots of videos on this.
