Well worth the money! Quick installation and it gave the expected results. My engine response is much improved and my over-all mileage is up almost 2 mpg!

Installation was fairly simple although if you have DBW you may need to use a longer hose for the coolant line that runs underneath throttle body. Saw a good increase in mpg did see a good difference in pick up midrange and was a good addition with the k&n intake. Well worth the $85. It does whistle but i only heard it when the radio was down.
