should the air filter box (lifetime) have water in it?

Asked by Sep 07, 2014 at 08:25 PM about the 2009 Ford Focus

Question type: Maintenance & Repair

Removed air filter box and saw water in the indicator mounted on the side and dumped water out of box.  Is this normal?  Should the filter be replaced?  Have had problems with acceleration and hesitation or missing.  Could air filter be part of the problem.  Love my franken focus but am getting frustrated.

The air filter box should not have water in it. You need to find how the water is getting in, and it's probably the reason your car is running poorly. Did you drive through a large puddle?

Yes but all my plastic under the fender and front bumper is missing
