2017 Toyota Avalon Hybrid Engine Air Filter Replacement

How often do you replace the air filter in your vehicle's engine? If you don't know or can't name the last time it was changed, this guide may be of great help to you!

Your filters should be replaced every 15,000-30,000 miles or 1.5-3 years depending on driving activity. Air filters help ensure the protection of the car’s engine by blocking out debris, bugs, dust, and any other irritants that permanently damage the engine’s internal structure; and when there are a lot of blockages, it can disrupt the air/fuel mixture.

By replacing the filter you can save a great amount of gas mileage on your vehicle. Overall, your car engine’s performance can slow when met with external irritants so it’s important to regularly replace its filters.

This process is really quick and easy and only requires one or two supplies! Before following this guide, make sure your car's engine has cooled completely and ensure you have the correct filter— not every car is the same!

Step-by-step instructions

Pull the hood release lever on the driver's side, to the left of the steering wheel, to release the hood latch.
This will only pop the hood.
Push the lever under the hood and lift.
Make sure the engine has been off for at least a few hours and is completely cooled.

The filter housing is located to the right of the engine.
Pull the metal safety clips on the filter housing toward you to release them and open the housing.
The box top may not come off completely; if you feel like you are forcing it open, ensure both clips are undone.
Avoid using excessive force when lifting the housing lid to prevent accidentally disconnecting the Mass Airflow (MAF) sensor electrical plug.

Carefully remove the old engine air filter.
Note the orientation of the old filter to make installing the replacement easier.

Before installing the new filter, use a microfiber cloth (or shop towels) to clean out the housing.
Make sure to wipe all dust, dirt, and other particles as well as removing any foreign objects.
You may need to hold the housing lid up with one hand while wiping with the other, as the lid may not come off completely.

Reference the orientation of the old filter and carefully place the new filter in the housing box.
If the filter doesn't securely fit or you feel as if you're forcing it into the housing, make sure it's facing the right way and all foreign objects have been removed from the box.

Align the lid with the bottom housing.
Push the clips away from you to secure the lid in place.
If the clips do not snap easily back into place, ensure the lid is aligned with the bottom of the housing. Do ***not*** force them.

Turn on the car to test the MAF and wait a few minutes.
If no alerts/warning lights come up, you have installed it correctly.
The dashboard containing the odometer and speedometer should look like the second image.
