Frank -
You can try BBB, if you really want to pursue the complaint, you might mention it to K&N themselves, as well as the company that owns the truck magazine (There is always a media company, and they might be interested to know about the false advertising that's going on in their "upright and honest" publication.)

Of course, you could also write a letter to the editor, asking for correction of falsehoods in the article. CC that note to those who "authored" the article, and executives of both the magazine and the parent company. Forward all correspondence to the BBB, titled with the report number, so it will be filed correctly.
