📋 Before You Begin

• 🚙 Park your CX-5 on level ground and apply the parking brake.
• 🌡️ Open the hood after the engine has cooled.
• 📦 Find the black plastic airbox connected to the large engine intake hose.
• 🧹 Sonipat’s dusty conditions can load a filter quickly, so keep dirt out of the clean side of the airbox.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the airbox clips

• Put on your safety glasses and nitrile work gloves.
• Locate the two metal retaining clips along the edge of the airbox cover.
• Pull each clip outward with your fingers until it releases.
• No bolts or screws normally need to be removed.

Step 2: Lift and release the airbox cover

• Lift the clipped edge of the cover only far enough to clear the filter.
• Move the cover slightly away from the fixed locating tabs on the opposite edge.
• Don’t pull hard on the intake hose or attached wiring.
• The plastic tabs break before they apologize.

Step 3: Remove the old filter

• Note how the old filter is positioned before lifting it out by its rubber edge.
• Check the dirty side for excessive dust, leaves, insects, or moisture.
• Don’t shake loose dirt over the open airbox.

Step 4: Clean the airbox

• Use the clean microfiber cloth to wipe loose debris from the lower airbox.
• Keep the cloth away from the outlet leading toward the engine.
• Don’t use compressed air because it can force dirt into the intake.

Step 5: Install the new filter

• Lower the new panel filter into the same position as the old one.
• Press gently around the perimeter so its rubber sealing edge sits flat in the airbox groove.
• Make sure no corner is folded, raised, or trapped outside the housing.

Step 6: Close the airbox

• Engage the fixed cover tabs with their slots first.
• Lower the opposite edge without pinching the filter seal.
• Press the cover down by hand and fasten both metal clips.
• No torque specification applies because the cover uses hand-operated clips.
