DIY: Infiniti QX4 & Pathfinder Air Filter 2001-2003

How to remove and reinstall engine air filter for the Infiniti QX4 & Nissan Pathfinder R50

May apply to earlier model years. 

Steps:
Pop open the hood and locate the engine air filter box. The box is behind the driver side head light assembly.

Locate the clips and pop them open. Pull the tray holding the air filter out. Clips are highlighted in red.


Remove the air filter and put in the new one. The filter goes in one way with the rubber seal facing the driver.


Dirty air filter removed. 

Dirty and clean filter comparison.



Check your filter with every oil change and see if it is dirty and clogged. A dirty air filter results in lower performance and MPG loss. Changing the filter is super quick and a cheap way of making sure you get the most performance out of your car. 

K&N 33-2031-2 High Performance Replacement Air Filter is the best air filter you can buy. The K&N Air Filter can be cleaned and re-used which saves a lot of money in the long run.

Purolator PA24278 PureONE Air Filter is pretty good if you don't want a re-usable filter.
