Mac Cold Air Intake

I put a Mac cold air intake on my 1995 mustang 5.0 and it makes a loud humming sound. Any thoughts?

Welcome to Stangnet.:SNSign:

About your Mac CAI, it could be one of two things that I could think of right off hand. First off, it may simply be the air traveling into the filter from the fender. It makes a sort of sucking ("woosh") sound when given throttle. Second, make sure all of your conections are tight and the heat deflector shield that is next to your fender is not vibrating against the fender itself. Those are the only two items I could think of based on your description.

Agreed with above. the pipe or filter might be hitting something (that filter hangs out a good ways into the fender gap).

I have check all connections and the heat sheild is not rattling, the noise is coming from the air filter when at idle.

probable just the sound of more air getting sucked in
