I went to another car store around here and none of the sell the NGK Coppers, where can i get them?

I went ahead and got the Denso Platinums, how good are these? Any input is greatly appreciated.

RETURN them. They could be the best plugs on the planet but they are not the right plugs for the maxima. Order some NGK coppers or platinums on-line from any number of good retailers.

I ran Denso in my '99 from about 62,000 to about 130,000. I went to the dealer and got OEM NGK plugs when I changed them a few months ago. I paid $16 per plug - I know I got ripped off - but I felt better about having the OEM plugs in there. In the future I will stick with NGK. My experience with the Denso was not bad at all, I just think that NGK makes a good plug that will work with my Max. My Max has 142,975 on it as of today and it runs fine.

my experience with denso has been very good in the max(better than ngk). its not oem, but hey, neither are any other mods going on around here. besides that, denso is high quality, not some crap plug you're throwing in there
