🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter box

• 🔸 Stand in front of the CR-V with the hood open.
• 🔸 Look on the left side (driver’s side) near the front corner: you’ll see a black plastic box with a large hose going to it. This is the air filter box.
• 🔸 Use the work light or flashlight to clearly see the clips and screws around the box.

Step 2: Identify clips and fasteners

• 🔸 On the air box lid, find the metal or plastic clips at the front and side edges.
• 🔸 Also look for any small bolts (usually 10mm) at the corners of the lid.
• 🔸 Use your 10mm socket on the ratchet to lightly check which fasteners are bolts and which are just clips. Do not overtighten or force them.

Step 3: Release the air box clips

• 🔸 Use your fingers to pull the metal or plastic clips away from the lid. They will “pop” off the lid and stay attached to the lower box.
• 🔸 If a clip is stubborn, gently pry it with the flathead screwdriver, but be careful not to break the plastic.
• 🔸 Make sure all visible clips holding the lid are released.

Step 4: Loosen any air box lid bolts (if equipped)

• 🔸 If your air box lid has bolts, use the 10mm socket, socket extension, and ratchet to loosen and remove them.
• 🔸 Turn the bolts counterclockwise to remove them. Place the bolts in a safe spot so they don’t fall into the engine bay.
• 🔸 These bolts are small and do not need high torque when reinstalling. When reinstalling later, snug them by hand until just tight; no specific torque spec is required.

Step 5: Lift the air box lid

• 🔸 Hold the large intake hose with one hand and gently lift the air box lid with the other.
• 🔸 The lid will hinge or slide back slightly. You don’t need to remove it completely; just open it enough to access the filter.
• 🔸 If it feels stuck, check again for any missed clips or bolts before pulling harder.

Step 6: Remove the old air filter

• 🔸 With the lid lifted, you’ll see the rectangular air filter sitting in the lower part of the box.
• 🔸 Grab the filter by the edges and pull it straight up and out using your hands (with mechanic gloves if you prefer).
• 🔸 Note how the old filter is positioned (which side is up and where the rubber or foam seal sits). Match this with the new filter.

Step 7: Clean out the air box

• 🔸 Look inside the lower air box for leaves, dust, or debris.
• 🔸 Use a clean shop rag to wipe out dirt from the bottom and corners of the box.
• 🔸 If needed, lightly spray the rag with throttle body/air box safe cleaner and wipe again. Do not soak the box or spray directly into the intake.

Step 8: Install the new air filter

• 🔸 Take the new engine air filter out of its packaging.
• 🔸 Place it into the lower air box with the rubber sealing edge facing up and seated firmly in the groove all the way around.
• 🔸 Make sure the filter sits flat and fully inside the box, with no edges bent or folded. A mis-seated filter lets dirt bypass it.

Step 9: Reinstall the air box lid

• 🔸 Carefully lower the air box lid back into place, making sure the edges of the lid sit over the new filter correctly.
• 🔸 Check that no part of the filter’s rubber seal is pinched or sticking out.
• 🔸 If your lid has tabs that fit into slots on one side, slide those into place first, then lower the rest of the lid.

Step 10: Secure clips and bolts

• 🔸 Snap the clips back onto the lid using your fingers. You should feel and hear them click into place.
• 🔸 If you removed bolts, use the 10mm socket, socket extension, and ratchet to reinstall them.
• 🔸 Turn the bolts clockwise until snug. Do not overtighten; just firm hand-tight is enough.

Step 11: Final check under the hood

• 🔸 Look around the air box area and make sure no tools, rags, or loose parts are left in the engine bay.
• 🔸 Gently wiggle the air box lid to confirm it’s secure and doesn’t move.
• 🔸 Remove the hood prop and carefully close the hood.

✅ After Repair

• 🔸 Start the engine and let it idle for a minute. Listen for any unusual hissing or whistling from the air box area (which could mean the lid isn’t seated correctly).
• 🔸 If you hear odd noises, shut the engine off, reopen the hood, and confirm the filter and lid are properly installed and all clips are fully latched.
• 🔸 There are no warning lights to reset for an air filter change on your CR-V.
• 🔸 Plan to inspect or replace the engine air filter about every 15,000–30,000 miles, or more often in dusty conditions.
