I know it's an old thread but I looked into these about 6 months ago.
I actually called up Russel Performance (Edelbrock) yesterday to find out why their application list only shows these bleeders for use on vehicles around 2006 and older. He said "I don't know." I said, "Well,... these should work on my 2015 Frontier, right?" He said "I don't know."
Then he says, "You can try to match your bleeder thread size up to one of ours and then try it out and see how it goes."
So as you can see, he wasn't helpful at all. And you would think a company owned by Edelbrock would have a little more product knowledge. And why on earth would they manufacture a product that isn't designed for use on vehicles made within the past 14 years? Or are they just too lazy to update their Application Guide? Who knows...
It looks like a pretty good idea, but I don't know if it's worth pulling my bleeders, measuring thread pitch, diameter, length, etc, and then trying to figure out which one of theirs might match.
