loud noise from air filter

[richardcw]

I have a horn type sound coming from air filter on 01 Lincoln tc.
What could this be?

You'll have to pull it apart and have a look. Could be a sensor module, a rats nest, bee hive.. etc.

Steven, I have taken the filter out and checked all the line, everything seems
ok but still have noise at entermitte times, what sensor could cause this

[radioconsult]

The air compressor for the air ride suspension is located under a plastic panel under the air filter box, it could be the cause especially if it is intermittent.

Sounds like you need a hooter hose.
