Owners of a 2011 Infiniti QX56 with 5.6 liter engine can select K&N's lifetime air filter 33-2456 as an alternative to the stock paper filter that requires replacement over and over. The 33-2456 is a washable, reusable air filter designed to increase power while providing outstanding filtration to help ensure long engine life.

Installation of K&N's replacement air filter for the Infiniti QX56 is simple due to its drop-in design. The unique shape of the 33-2456 panel air filter allows it to fit into the stock air box and seal tightly against it.  K&N air filters are designed to increase horsepower and torque.  Adding performance to your SUV is as easy as switching air filters. 

K&N's pleated, depth-loading design allows the 33-2456 to perform for up to 50,000 miles before cleaning is necessary. Cleaning your K&N Infiniti QX56 air filter is easy and can be done using one of K&N's Recharger kits and following a set of simple cleaning instructions.

The 33-2456 is backed by the famous K&N Million Mile Limited Warranty and will be the last air filter your Infiniti QX56 will ever need.
