Owners of other Toyota and Lexus vehicles such as the Camry, C-HR, Venza, Avalon, 86, Sienna, Tacoma, RAV4, Highlander, 4Runner, Sequoia, IS 350, RX 350, UX 200, GS 350, IS 300 and ES 350 may also find these DIY instructions to be helpful.

The OEM (original equipment manufacturer) engine air filter part number is Toyota 17801-F0020 (also known as part # 17801F0020).

A few compatible replacement aftermarket filters with their part numbers are as follows: EcoGard XA10586, K&N 33-3080, Beck/Arnley 042-1917 and Mann Filter C 17 008.

No tools are required to access and replace the filter.

A wet/dry shop vacuum may be useful if you'd like to clean the original filter or remove any debris in the air box.

The first two steps are to open the hood and move to the right (driver) side of the engine bay.

The rectangular shaped black plastic engine air filter housing is located behind the driver side headlight housing and in front of the fuse box and 12V automotive battery.

There are two metal latches that secure the top half of the air box to the bottom half.

Flip the front right metal latch down and away from the air box cover.

Slide the air box cover towards the right (driver) side to release the two tabs on the left side from the slots attached to the bottom half of the housing.

Pull the old filter straight out of the bottom half of the housing.

Check the bottom of the air box for any sand, leaves, insect or other debris.

Clean out any debris with the crevice attachment of your vacuum.

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

I recommend buying the EcoGard XA10586 engine air filter since it has excellent reviews on Amazon.

If you'd rather have a washable and re-usable filter, buy the K&N 33-3080 engine air filter that has a 10 year and million mile limited warranty.

If the old filter is relatively clean, just tap out the large debris and remove any fine dust with the vacuum cleaner.

Lower the new filter into the bottom half of the air box.

Make sure the filter is fully seated in the housing.

Lower the right side of the cover down into place.

Flip up the two metal latches and snap them back into place over the air box cover.

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

According to the maintenance schedule in the owner's manual, the service interval for changing the engine air filter is every 30,000 miles or every 36 months.

Don't forget to write down the filter change in your car's service records.
