This automotive maintenance tutorial was specifically written to assist owners of the eleventh generation (2014, 2015, 2016, 2017 and 2018) Toyota Corolla in cleaning or changing the engine air filter element for the 2ZR-FE 1.8 liter inline four cylinder motor.

Owners of other Toyota, Lexus or Scion vehicles such as the Yaris, Matrix, Prius, Camry, RAV4, Sienna, Tacoma, Tundra, FJ Cruiser, Venza, Highlander, Avalon, Sequoia, Land Cruiser, IS 250, ES 350, GS 350, tC, xB, xD, iQ and FR-S may also find these DIY instructions to be helpful.

A few compatible replacement filters with their part numbers are as follows: Fram CA10190, Toyota 17801-0T030, Wix 49172, ACDelco A3103C, K&N 33-2360, , Ecogard XA5650, Hastings AF1307, Purolator A25655, Mann Filter MA 1191, POTAUTO MAP 6001, Premium Guard PA5655, Pentius PAB10190, Beck Arnley 042-1711, GKI AF10190, MAHLE Original LX 2792 and Champion CAP10169.

No tools are needed to access and replace the filter.

Release Left Side Fastener
2nd Metal Latch Released
Pull Off Air Box Cover
The first two steps are to open the hood and then move to the right side of the engine bay.

The engine air box is located to the right of the engine, behind the 12V automotive battery and next to the fuse box.

The top half of the engine air box is held in place by two metal latches.

One latch is on the right rear corner and the other is on the left side.

Flip the two metal latches down and off the air box cover.

Lift the top half of the air box off the bottom half to reveal the old filter.

Pull Out Old Air Filter
Old Air Filter Removed
Clean With Vacuum
Pull the old air filter out of the bottom half of the air 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 cleaner.

If the old filter is dark grey or black and clogged with dirt, dust, soot, pollen, insects, leaves, twigs and other debris, it should be replaced with a new element.

I recommend buying either the OEM Toyota 17801-0T030 filter or the Fram CA10190 filter since they have excellent reviews on Amazon.


Clean Out Bottom Half
Replace Wire Harness
Secondary Upper Air Filter
If your vacuum cleaner has a crevice attachment, clean out any sand or debris in the bottom of the air box.

There is a second permanent charcoal filter in the top of the air box. The secondary filter helps to reduce emissions by absorbing fuel vapors after the engine is shut off.

Install New Air Filter
Insert Tabs In To Slots
Secure Metal Latch
The air filter has one square corner so that it can only be installed in one way.

Lower the new air filter in to the bottom of the air box.

Re-insert the tabs on the air box cover in to the slots on the bottom half of the air box.

Flip Up 2nd Fastener
Replace Wire Harness
Engine Filter Replaced
Flip the two metal latches up and over the air box cover to secure it in place.

If the wire harness popped off the air box cover, push it back in to place.

Double check that the two halves of the air box are flush together with no parts of the new filter visible.
