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.
