What are the measurables? Or are they just "designed" to do so with no difference, like so many food "supplements" that purportedly "support" normal bodily functions?
(OT: Thanks to Orrin Hatch for deregulating the food supplement industry. Now we are awash in totally useless products with ridiculous claims as long as there is the meaningless disclaimer that they do not treat any disease or medical condition after representing that they do precisely that.)

Scott:
I have NO IDEA...yet.
A few of us here who are very familiar with K&N products and their performance over the years have orders on the way. Mine will get to me 8/6. Then, after a quick and easy install I’ll try them out on my “seat dyno” and report back.

No noticeable gain on my butt dyno here. Installed a set last week
It looks like the $25.00 gift card is only for air intake purchases, not air filter purchases. ($10 gift card for cabin filter purchases.)
I still ordered a couple.
If you want a free K&N cap, though, you can use this link. I'll also get a cap, but I don't really wear caps, so...
Ordered as well. If I can get a bit more intake sound, then I'll be happy.
Cars with filters supposedly have shown a slight increase in trap speed at 1/4 mile.

We all need to share our experiences on how well they work.
Best regards

So, IF, (and it's a huge 'if'), the replacement air filter gives you an additional 10hp, it essentially means that in a GT R it increases hp by 1.7% if you use the factory rating of 577hp. Less if you agree as I do that the car actually puts out more than 600hp.
Hopefully some change in induction 'noise' makes it worthwhile! lol

I posted the following information here 6/1 which I obtained from the Renntech site;
Has anyone else installed theirs, yet? I put mine in, tonight, and took a neighbor for his first ride.
Of course, I had to show him the Race Start. It may have been my imagination, but I don't think
I've felt the blood rush to the back of my head like that, before. It was awesome. Neighbor said
that he got dizzy.
Maybe some of it had to do with the extra weight that I got out of the air cleaner:
I have had mixed results with K&N... in some cars I have felt "what I think is an improvement" in others I have not. I would not expect to see a 10 HP increase... not a chance. I also think BMC flows better...

To whomever used that link to order their filters, a woman in my office thanks you for the cap. ;-)
