accufab 84.5mm throttlebody and kn intake review.
Both of these products fit great, and had a slight power increase along with a 2 mpg city increase, no noticeable increase on the highway. The Kn Typhoon intake has an aluminum tube which gets quite hot at idle, and increases intake air temperature by about 10 degrees c, but once the vehicle is in motion it has the same air intake temperature, as external air temperature. I did not notice a power increase, but my wife noticed it over the course of a week, she asked what I did to the car and said it felt more "snappy" and she liked it. There is a noticeable sound difference and it eliminates the noise tube, does not sound louder but has a deeper growl to it. Water does not leak into the intake it has an enclosed box which utilized the factory scoop. The engine cover, covers the throttle body and the hose couplers for a nice looking fit.
