Why Replace the Air Filter?

What the Air Filter Does

The engine air filter prevents dust, pollen, debris, and insects from entering the intake system. Keeping it clean helps ensure:

• Better airflow to the engine
• Improved fuel efficiency
• Optimal engine performance
• Reduced internal engine wear

Signs the Filter Needs Replacement

• Dark, dirty, or clogged appearance
• Engine feels sluggish, louder, or less responsive
• Increased fuel consumption
• Service interval reached (or dusty driving conditions)

Preparation

Tools and Materials Needed

• Replacement air filter compatible with Toyota RAV4 2019-2021
• Gloves (optional)
• Owner’s manual for reference

Safety Tips

• Park on flat ground and apply the parking brake
• Turn off the engine and allow it to cool
• Open the hood and secure it with the support rod
• Avoid touching hot components

Step-by-Step Air Filter Replacement

Locate the Air Filter Box

1. Open the hood and secure it.
2. The air filter housing (airbox) is located toward the front-right side of the engine bay.

Open the Air Filter Housing

1. Locate the retaining clips on the airbox cover (usually two).
2. Release the clips.
3. Slide the top of the housing slightly toward you (about an inch) to release the rear locking tabs.
4. Lift the front of the housing lid to expose the filter.

Remove the Old Filter

• Pull the filter straight out.
• Note its orientation — the long side runs front to back.
• Wipe out any loose debris inside the airbox (do not use liquids or sprays).

Install the New Filter

1. Insert the new filter in the same orientation, making sure it sits flat.
2. Check that the rubber lip seals evenly around the housing.
3. Slide the cover back so the rear tabs engage properly.
4. Close the clips securely.
5. Lower and close the hood.

Maintenance Tips

Recommended Replacement Interval

Check and replace the filter every 20,000–30,000 km (12,000–18,000 miles), or sooner if you drive in dusty areas.
