🔧 GX460 - Engine Air Filter Replacement

Your GX460’s engine air filter keeps dust and debris out of the engine. Replacing it restores airflow, helps fuel economy, and protects the mass air flow (MAF) sensor from contamination.

Difficulty Level: Beginner | Estimated Time: 0.2-0.5 hours

Assumption: Stock air box (no aftermarket intake).

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter housing

• Look for the large black plastic air box connected to the intake tube (the tube leading toward the engine).
• Use safety glasses and nitrile gloves before reaching around the engine bay.

Step 2: Unclip and loosen the air box cover

• Release the metal retaining clips on the air box cover by hand.
• If the cover won’t lift easily, loosen the intake hose clamp at the air box using a 10mm socket and 1/4" drive ratchet (or a flathead screwdriver if it’s a screw-type clamp).
• Only loosen enough to lift the cover.

Step 3: Open the air box and remove the old filter

• Lift the air box lid up and away just enough to access the filter.
• Pull the old filter straight out.
• Use a shop towel to wipe out loose dirt inside the lower air box. Do not push debris down the intake.

Step 4: Install the new air filter

• Place the new filter into the lower air box the same way the old one came out.
• Make sure the filter gasket (rubber sealing edge) sits flat all the way around. No gaps.

Step 5: Close up the air box

• Lower the air box lid back into position and confirm it seats evenly.
• Reinstall and lock all the retaining clips by hand.
• If you loosened the intake clamp, tighten it using a 10mm socket and 1/4" drive ratchet (or flathead screwdriver as applicable) until snug and the hose cannot rotate.
• If your air box has any 10mm lid bolts (some variants do), tighten them with a 10mm socket and 1/4" drive ratchet: Torque to 5 Nm (44 in-lbs).

✅ After Repair

• Start the engine and let it idle for 15–30 seconds.
• Listen for any whistling or hissing (a sign the air box isn’t sealed or the clamp is loose).
• Do a quick visual check that all clips are fully latched and the intake tube is fully seated.
