Okay so maybe its the guy in me but the temptation of the shiny chrome tubing to the nice k & N filter looks very appealing to me, but at the same time the price persaudes my decision making process to an idle... I mean ya they are a little pricey i dont care who you are... I have read through a few threads on here and i have noticed that some love them and others hate them. One member posted that K&N's hp gains only come at 4K rpms... and like he said my highway driving is normally lower than 3K. So i need your guys help are these things worth it if your not using a programmer... and also if you are, are they still worth the cost.
