2014 Altima Engine Air Box
Flip Down Metal Latch
Release Left Side Latches
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.

Secure Other Fasteners
5 Latches Secured
Engine Air Filter Replaced
Flip up the 5 metal 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.
