# How to install velocity cold air intake?

Short answer... it depends!based on if you're using a kit or doing it yourself. if doing it yourself you need so kind of air scoop, such as a bonnet scoop. you then need to use PVC piping or hosing to direct the cold 'outside' air to your intake manifold.Best idea is to mount a bonnet scoop. form (MORE)

# How does the velocity of sound in air depend on temperature?

The speed of sound in air changes clearly with temperature, a little bit\nwith humidity - but not with air pressure (atmospheric pressure). \n The words "sound pressure at sea level" are incorrect and misleading in \nthe case of "speed of sound".
