This
automotive maintenance tutorial was specifically created to assist
owners of the 2nd generation (2004, 2005, 2006, 2007, 2008 & 2009)
Toyota Prius hybrid in cleaning or changing the engine air filter
element for the 1NZ-FXE 1.5 liter inline four cylinder motor. Owners of other vehicles equipped with one of the Toyota NZ family of engines such as the Prius C, Yaris, Corolla, Axio, Fielder, Echo, Scion xA, xB, Auris, Premio and Sienta may also find these DIY instructions to be helpful. A few compatible replacement engine air filters with their part numbers are as follows: Toyota OEM 17801-21040, Fram CA10159, K&N 33-2329, Wix # 49116, Premium Guard PA5698, Pentius PAB10159, Beck Arnley 042-1729, Purolator A25698, Mahle LX 2695 and Mann Filter MA 1194. No tools are needed to replace the filter. A wet/dry shop vacuum can be useful for cleaning the bottom half of the air box and the existing OEM filter element in order to re-use it. |

Flip Open 2nd Latch |
2nd Metal Latch Released |
Open 3rd Metal Latch |
The black plastic
engine air box is located in the center of the engine bay. The top cover of the air box is held in place by three metal latches on the front edge and a fourth latch near the rear left corner. Flip up the bottom of each metal latch on the front edge to release them and then pull the metal hook at the top away from the air box. |

4th Latch - Back Left Corner |
Lift Off Air Box Cover |
Air Box Cover Removed |
Then move to the
left rear corner of the air box and flip down the 4th metal latch to release
it. Pull the top half of the air box off and set it aside in a safe place. |

Remove Old Engine Air Filter |
Inspect Both Sides |
Clean Bottom Half Air Box |
Pull the old engine
air filter straight 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. If the old filter is dark grey or black and clogged with dirt, dust, leaves, insect, twigs, pollen, hair and other debris, it should be replaced with a new element. If you have a crevice attachment for your vacuum, clean out any sand or other debris from the bottom half of the air box. |

Clean OEM Air Filter |
Install Filter In Box |
New Filter Installed |
Line up the cleaned
or new engine air filter and lower it down in to the bottom half of the air
box with the rectangular opening situated on the right (driver) side. I recommend using the Toyota Genuine Parts 17801-21040 engine air filter. If you would like to have a washable and re-usable filter, choose the K&N 33-2329 engine air filter. |

Three Tabs On Back Side |
Insert Tabs In Slots |
Lift Latch Over Top Cover |
Line up the three
tabs on the rear edge of the air box cover with the slots on the bottom half
of the air box. Insert the tabs in to the slots and lower the top half of the air box in to place. |
||
Snap Down To Secure Latch |
Secure 3 Front Latches |
Secure 4th Metal Latch |
Raise the three
metal latches on the front edge of the air box, secure the hook over the top
half and push down the metal ring to secure the fasteners in place. Raise the 4th metal latch near the left rear corner of the air box and snap it over the top half of the air box. Double check that all four of the fasteners are secured and the two halves of the air box are flush together all the way around. Be sure to record the filter change in your vehicle's service records.
