K&N does it again
They're quick and easy to install. Honestly- I buy the K&N cold air intakes because the noticeable improvement of the engine note. Furthermore, the throttle response is a little better from stock. However, be aware, around shift points, there is an annoying whistle that resembles that of a throttle body spacer. Hence, the 4 star rating. FYI: Cold Air Intakes give meniscal power and MPG gains. Any MPG gains I might have gotten are destroyed by my led foot- The engine just sounds too good with 77.
