Then let them know the truth is that they do let the engine "breath" easier and thus makes more hp than with stock restrictive filters. If you have the stock filters installed someone with less restrictive performance filters will turn better times. That's the pure and extremely simple truth. 
The fact that you're older than me by 3.5 years means what??? :roll:

Companies like this make a fortune based on junk science and pure B S. I always have a laugh when someone talks about their HP gains when changing air filters or putting additives in their oil pan. If you want to add cheap HP, add tuned headers and exhaust. Its the ONLY cheap H you can buy, everything else costs REAL money. All you have to do is go to the strip and change filters between runs, do it more then once each , and you'll save money to buy some real HP.
I beg to differ,the K&Ns did help mine breath better than the stock filters, that were the same price about $60. delivered. But I did have about 10k miles on my paper stock ones.
And if you do get too much oil on them you're screwed.

You said how old you were, so I answered, means nothing. I didn't say the engine wasn't less restricted, I said they don't MAKE HP. The point is the amount of difference cannot be felt. You can say it can forever, but the dyno doesn't support it and never has. Yes they allow slightly better airflow (its less than 2%). If these things worked the factories would put them on. They aren't worth the problems they can potentally cause. As I said if you like them and don't mind the risk (however small) knock yourself out.

This is better than the Bush vs Kerry debate.
Anyway, I plan to get mine dyno'd with stock filters then add K&Ns and get it re-dyno'd.
Should clear up some of the differences of opinion with fact.

Re: K&N.....Yikes!
To add in my fifty cents on the K&N filter discussion. Is that with my experience with them on my ride, they do seem to have better air flow and a slightly noticeable gain but I never had a problem with them. I just think it's better to have them, then not have them. It doesn't change hp dramatically but one thing I noticed is, that when I had a new car with clean oil after I installed a K&N a few weeks later, the oil is already dirty. I have no clue if that is harmful to engine but I think their filtration is not at 100%.

Re: K&N.....Yikes!
As much as I like the idea of the K&N's, they can cause some Mass Air Flow issues. It is common on Mustang GT's that they will cause some knock due to the oil getting on the "wire", out of the box. I've kept the Crossfire stock having experienced this.
