Installed on my 2013 Ford Fusion 1.6L, it was an easy job, I removed the old filter from the compartment behind the glove box and then put in the new wix filter, you may need to use a little force as it seems trapped, hit once about 2/3 of the way but overall it went in easily. (Actually I had to use it twice because I didn't pay attention to the airflow arrow the first time, the second time it was pretty easy). Up until now everything was fine with the air quality, the stale air is now gone…
