| This
automotive maintenance tutorial was specifically written to assist
owners of the fifth generation (2013, 2014, 2015 and possibly also
the revised 2016 model year) Nissan Altima sedan in cleaning or
changing the engine air filter element for the QR25DE 2.5 liter
inline four cylinder motor. Owners of other Nissan or Infiniti vehicles such as the Versa, Maxima, Juke, Rogue, Murano, Xterra, Pathfinder, Sentra, Cube, Armada, Leaf, Quest, Frontier, 370Z, GT-R, Titan, G25, G37, M35 and M37 may also find these DIY instructions to be helpful. A few compatible replacement engine air filters with their part numbers are as follows: Fram CA11450, K&N 33-2478, Ecogard XA10003, Mahle LX3498, Beck Arnley 042-1843, Pentius PAB11450 and Wix # 49073. No tools are needed to replace the filter. A wet/dry shop vacuum may be useful for cleaning the existing element in order to re-use it. |

 Rear Left Corner Latch |
 Release Right Side Latch |
 Lift Top Half Air Box |
| The engine air box
is located at the right rear area of the engine bay just behind the 12V
automotive battery. Flip down the 5 metal latches to release the top half of the air box. Lift the air box cover to access the old filter. |

 Pull Out Old Filter |
 Inspect Both Sides |
 Clean With Vacuum |
| Pull the old filter
out of the bottom half of the box. Inspect both sides of the old filter. If the old filter is relatively clean, just tap out the large debris and remove any fine dust with a vacuum. If the old filter is dark grey or black and clogged with dirt, dust, hair, insects, leaves, pollen, twigs and other debris, it should be replaced with a new element. I recommend going with the Fram CA11450 engine air filter since it has great reviews on Amazon. If your vacuum cleaner has a crevice attachment, clean out any dust or sand in the bottom half of the air box. |

 Insert New Filter |
 Close Top Half Air Box |
 Raise Metal Latch |
| Due to the unique
shape of the air filter, it will only fit in to the air box in one way. Install the new filter in to the bottom half of the air box. Close the top half of the air box over the bottom half. |

 5 Latches Secured |

latches and push them over the top half of the air box to secure it in
place. Double check that the two halves of the air box are flush together at every edge. For more, check out my other
