You did look at the OTHER side of the filter, right? The side you see when you first take off the cover is the engine side.hyperion said:It just takes a couple minutes to pop the clips and take it out. Mine with 12,000 miles on it looks as good as the day I drove out of the dealership when new. It gets changed when it gets dirty!
Just changed my engine air filter at 25,000 miles, also "not entirely cruddy". It was not quite dirty enough to change at 20,000 miles. Will now look for the MPG increase.redwein said:I changed my air filter at 25,000 miles and noticed a consistent 3 MPG increase. The old one looked pretty dirty but not entirely cruddy.
