K&N 33-2431 Air Filter fits 2010 Mustang GT 4.6L 3V, 2011-2013 Mustang GT 5.0L 4V, and 2011-2013 3.7L V6

These 2010-2014 Mustang K&N Filters are designed to be a simple drop in application and outflow any other filter on the market, up to 900 cfm, for power gains of up to 15 hp. K&N air filters for 2010-2014 Mustang use a special surgical cotton fabric sandwiched between aluminum screen wire. The square holes in the cotton catch tumbling air and straighten it out. Since air moving in a straight line flows faster, these K&N filters can actually improve airflow. So, if you want to replace your Mustang's old air filter, or if you just want increased airflow over your air factory Mustang filter, then you need to get one of these K&N air filters.
