This BD Cold Air Intake made my milage worse. Any thoughts as to why?
so your getting more air its just hot, you need the box that goes around the filter. check the driver side of your valvecover to be sure what hp/tq you have
The hot air could decrease mileage, but 3 mpg seems like too much. There are a lot of things that effect mileage, a slight wind can make a huge difference when towing.
Gotcha. Yeah I removed mine in favor of a Airaid MIT. Be sure to leave the vanes in the lower elbow, they help turbo performance.The intake tube. There is a hard plastic piece that goes between the turbo and air box. I have the factory one off and the bd one with no restriction in it's place.
