This is a great cabin filter for her 2013 Honda CR-V... It was relatively easy to get the glove box down just enough to allow me to get my hands on the cabin filter cover, and pull it out... It was so dirty!!! The new one immediately made the air coming into the car, so much nicer to breathe.... Great filter...Perfect fit.... Thanks, Bosch !!!

Works fine 3 months in

Installed a few months ago, before the winter. I was chasing a no-start after replacing the old battery. We've seen single digit temps in the meantime and it is working well. The fit is perfect in a 2010 focus. If you can slide it in from the side and not drop it in from the top, you can replace it without taking off the intake manifold. There are useful videos online showing this. Good luck!

Will be returned as soon as I have a replacement.

When engine is cold starter works fine with engine is hot. It will free wheel the starter motor, but not kick the starter gear into the ring gear on the motor. Watch video and listen it actually did it twice at this location but I didn’t catch the first one on the video.
