Steps

1. Step 1: Prepare the vehicle and parts

   • Park on a level surface and turn the engine off.
   • Remove the key and allow hot engine components to cool.
   • Confirm you have the correct replacement air filter by matching the part number to your vehicle.
   • Open the hood and locate the engine air filter housing, using the owner's manual if needed.

   Check: The engine is off and cool. · You have the correct replacement filter. · You can clearly identify the air filter housing.

2. Step 2: Open the air filter housing

   • Inspect how the housing is secured; it may use clips, screws, or tabs.
   • Release the clips or loosen the screws carefully without forcing anything.
   • Lift or open the housing enough to access the filter while noting how everything is positioned.

   Check: All clips or screws are released without damage. · The housing is open enough to remove the filter. · You understand how the cover fits back into place.

3. Step 3: Remove the old filter

   • Lift the old air filter straight out of the housing.
   • Note the filter's orientation and how the sealing edge sits in the housing.
   • Check the old filter for heavy dirt, leaves, or damage.

   Check: The old filter is fully removed. · You know the correct orientation for the new filter. · No loose debris has fallen into the intake opening.

4. Step 4: Clean the housing

   • Inspect the inside of the air box for dust, leaves, or other debris.

   • Do not push dirt into the intake tube or use excessive force.

   Check: Loose debris is removed from the housing. · The intake opening remains clean and unobstructed. · The housing sealing surfaces are clean enough for the new filter to seat properly.

5. Step 5: Install the new filter

   • Place the new filter into the housing in the same orientation as the old one.
   • Make sure the filter sits flat and the sealing edge is fully seated all the way around.
   • Reposition the housing cover carefully without disturbing the filter.

   Check: The new filter is installed in the correct orientation. · The filter is sitting flat with no folded edges or gaps. · The housing cover aligns correctly over the filter.

6. Step 6: Close the housing and verify

   • Secure all clips, tabs, or screws evenly.
   • Check that the cover is fully closed and nothing is pinched or misaligned.
   • Start the engine and listen for any unusual intake noise or rattling.
   • Look for any warning lights and recheck the housing if anything seems off.

   Check: All clips, tabs, or screws are secured. · The housing is fully closed and sealed. · The engine runs normally with no unusual sounds or warning lights.
