Some times you just know when it needs to be changed and it's that easy. This is a prime example where no words were needed when our Covington driver saw the filter.....it was a done deal. It is a shame you can't see these things from the outside and in this case the filter itself isn't that bad it's the animal that was making a home in the filter that was the issue. When you get home from a trip and haven't moved your car or truck take a look under it after moving it to see if any debris is under the vehicle parking spot. If so let us check it out here at Elite Automotive LLC in Covington to see just what it may be before they become TOO COMFORTABLE! It's our job to help you avoid high repair costs.
