Step-by-Step Instructions

Follow these steps carefully

1

Open the hood and locate the engine airbox

Open the hood of the Equus and secure it, then find the large plastic engine air filter box connected to the intake tubing in the engine bay. Take a moment to identify the lid and its fasteners before touching anything. Completion looks like the airbox clearly identified with access to its lid.

2

Open the airbox lid

Release the fasteners around the airbox lid and lift the lid enough to expose the panel filter inside. Work carefully so the plastic lid and fasteners are not cracked or broken. You are done when the lid is open and the old filter is visible.

3

Remove the old engine air filter

Lift the old panel filter out of the lower housing, noting which way it was oriented so the new one goes in the same way. Keep your hands and tools clear of the open intake opening while the filter is out. Completion is the old filter removed with the empty housing visible.

4

Clean debris from the airbox

Wipe or vacuum out any leaves, dust, and grit that collected in the bottom half of the airbox, since debris left behind will immediately load the new filter. The step is complete when the housing is clean and dry.

5

Install the new engine air filter

Set the new panel filter into the lower housing in the same orientation as the old one, making sure its sealing edge sits flat and even all the way around. An unevenly seated filter lets unfiltered air bypass into the engine. You are done when the filter lies flat with no gaps at the seal.

6

Close the lid and refasten it

Lower the airbox lid back over the new filter without shifting the filter out of its seat, then re-engage every fastener until the lid is held down evenly. Completion looks like a fully closed airbox with no visible gap between the lid and housing.

7

Verify the installation

Tug gently on the airbox lid to confirm it is secured, then close the hood and start the engine. Listen for a normal idle with no unusual whistling that would indicate an air leak at the box. The job is complete when the engine idles normally and the airbox is sealed.

All Done!

Test your repair before closing everything up. If something doesn't work right, double-check your steps.

⚠️ Common Mistakes to Avoid

  • • Installing the new filter upside down or cocked in the housing, which breaks the seal and lets dirty air into the engine.
  • • Leaving one of the airbox fasteners unlatched, allowing the lid to vibrate loose and whistle or admit unfiltered air.
  • • Skipping the airbox cleaning step, so trapped leaves and grit immediately contaminate the new filter.
