2014 Tucson Engine Air Box
Flip Down Metal Latch
Release 2nd Metal Latch
This automotive maintenance tutorial was specifically written to assist owners of the 2nd generation (2010, 2011, 2012, 2013, 2014 & 2015) Hyundai Tucson SUV in cleaning or changing the engine air filter element for the Theta II 2.4L I4 motor.

Owners of other Hyundai and Kia vehicles such as the Accent, Elantra, Sonata, Azera, Veloster, Tiburon, Genesis, Lavita, Veracruz, Santa Fe, ix35, Equus, Cadenza, Forte, Optima, Rio, Soul, Sedona, Sorento, Spectra and Sportage may also find these DIY instructions to be helpful.

A few compatible replacement air filters for both the "Nu" 2.0L or Theta II 2.4L I4 engines with their part numbers include the following: Purolator A26118, Fram CA10889, Beck Arnley 042-1813, Ecogard XA6118, Pentius PABT2066, Premium Guard PA6118, Mahle LX 3026, K&N # 33-2451 and Hastings AF1450.

No tools are needed to replace the filter.

A wet/dry shop vacuum can be useful for cleaning the OEM filter element in order to re-use it or for cleaning the bottom half of the air box.

Release 4th Metal Latch
Lift Off Top Cover Air Box
The engine air box is located at the front right (driver) side of the engine bay.

There are four metal latches holding the top half of the air box in place to the lower half with one located at each corner.

Flip the metal latches down off the top half of the air box.

Lift the top cover off the air box to access the filter.

Pull Out Old Filter Element
Old Engine Filter Removed
Inspect Both Sides
Pull the old filter out of the box and inspect both sides of it.

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, pollen, leaves, twigs, insects, hair and other debris, it should be replaced with a new one.

I recommend buying the Beck Arnley 042-1813 engine air filter since it has excellent reviews.

If you'd rather have a re-usable filter, go with the K&N 33-2451 which will need to be washed and re-oiled every 50,000 miles.


Clean With Vacuum
Clean Bottom Half Air Box
Insert New Air Filter
If your vacuum has a crevice attachment, clean out any sand or debris in the bottom half of the air box.

Insert the cleaned or new filter element in to the lower half of the air box.

New Engine Filter Installed
Replace Top Half Air Box
Secure 4 Metal Latches
Lower the top half of the air box over the lower half.

Flip the four metal latches up over the top half of the air box and snap them in place.
