K&N Air Intake System
K&N CLAIMS that there air intake will add 23+ HP
Has anyone had any experience with this product?
Does it work as advertized?
Easy to install?
any feedback would be appreciated.
here is the add. it just seems too good to be true so i am guessing that it is!

RE: K&N Air Intake System
It doesn't add 23 peak hp, it adds 20ish hp in the midrange. Overall gain is about 3-4hp as I have tested on my dyno. All the units I have tested have also thrown check engine lights.
