Are these an extra option or standard? I looked through Infiniti.com and couldn't seem to find any info on this.

Is it just for m45's? or m35's as well?

I'm more interested in the cooled seats, do they actually work well?

Thanks a lot

 

I actually went through the Infiniti site again with a fine tooth comb and it looks like it is standard equipment on the M35 sport.

The real question now is, how well do they work?

 

Yes, Mike they are standard on both M35 & M45....and they work very well in my ride. Heating is good, actually better than my Coupe, and the cooling is very good, altho of course it takes a few minutes to cool the seat.
Great feature for my old rear.
