🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the engine air filter box

• 🧰 Stand at the front of the vehicle and look slightly to the left (driver side) of the engine bay.
• 🧰 Find the black plastic box with a large air hose (intake duct) attached to it; this is the air filter housing.
• 🧰 Make sure you can see the housing cover and the screws along its edges.

Step 2: Clear access around the air box

• 🧰 Move any loose items (rags, tools) away from the area so you have space to work.
• 🧰 If there are small wire clips or a harness clipped to the air box, gently pop them out by hand or with the flathead screwdriver so they don’t pull tight.
• Don’t pull hard on any wires

Step 3: Loosen the intake hose clamp

• 🧰 Locate the metal clamp where the big rubber intake hose connects to the air box cover.
• 🧰 Use the 8mm socket and 1/4" ratchet to turn the clamp screw counterclockwise until the hose feels loose on the plastic neck.
• 🧰 If you prefer, you can use the flathead screwdriver instead of the 8mm socket on the clamp screw.
• Do not remove the clamp screw completely

Step 4: Remove the air box cover screws

• 🧰 Find the screws along the top and sides of the air box cover (usually 4–6 screws).
• 🧰 Use the 8mm socket, 3" extension, and 1/4" ratchet to remove each screw by turning counterclockwise.
• 🧰 Keep the screws in a small container or pocket so they don’t fall into the engine bay.
• Check all edges so no screw is missed

Step 5: Lift and tilt the air box cover

• 🧰 Gently pull the loosened intake hose off the air box cover neck using your hands.
• 🧰 Carefully lift the air box cover straight up; you may need to wiggle it to free plastic locating tabs.
• 🧰 Tilt the cover toward the front or side to expose the filter inside; do not yank if a sensor plug or hose is attached.
• If a sensor is attached, just set the cover nearby carefully

Step 6: Remove the old air filter

• 🧰 Note how the old filter is positioned (which side faces up and which edge sits in the housing groove).
• 🧰 Grab the filter by its plastic or rubber frame and lift it straight up and out of the housing.
• 🧰 Inspect the bottom of the air box for leaves, dust, or debris.

Step 7: Clean the air box

• 🧰 Use a shop towel or microfiber cloth to wipe out any loose dirt and debris from the bottom and sides of the air box.
• 🧰 Do not use water or cleaners inside the air box.
• 🧰 Make sure no pieces of debris or cloth fibers are left behind.
• Cleaning helps the new filter last longer

Step 8: Install the new engine air filter

• 🧰 Take the new filter and match its shape to the housing so it sits the same way as the old one.
• 🧰 Place the filter into the air box, making sure the rubber or foam sealing edge sits flat all the way around.
• 🧰 Press gently around the edges with your fingers to confirm it is fully seated and not tilted.
• The cover should sit flat without forcing it

Step 9: Reinstall the air box cover

• 🧰 Position the air box cover back over the new filter, lining up any plastic locating tabs at the rear or sides of the housing first.
• 🧰 Lower the cover straight down so the edges meet evenly and there are no gaps.
• 🧰 Slide the intake hose back onto the plastic neck of the cover.

Step 10: Reinstall and tighten the air box screws

• 🧰 Start all the screws by hand to avoid cross-threading (going in crooked).
• 🧰 Use the 8mm socket, 3" extension, and 1/4" ratchet to tighten each screw evenly by turning clockwise.
• 🧰 Snug the screws; do not overtighten, as the cover is plastic. Typical spec for these small screws is about Torque to 3–4 Nm (27–35 in-lbs).
• Stop when the screw just stops and feels firm

Step 11: Tighten the intake hose clamp

• 🧰 Make sure the intake hose is fully seated over the plastic neck on the air box cover.
• 🧰 Use the 8mm socket or flathead screwdriver to tighten the hose clamp screw clockwise until the hose is snug and cannot rotate by hand.
• 🧰 Typical clamp tightness is about Torque to 3–4 Nm (27–35 in-lbs), but “firm, not crushing” is the goal.
• A loose clamp can cause air leaks and check-engine lights

Step 12: Reattach any clips or wires and final check

• 🧰 If you unclipped any wiring harnesses from the air box, push them back into their clips by hand.
• 🧰 Visually inspect the air box all around: no gaps, all screws installed, hose fully on and clamp tight.
• 🧰 Remove tools and rags from the engine bay.

✅ After Repair

• 🔑 Start the engine and let it idle for a minute; listen for any unusual hissing sounds around the air box that could indicate an air leak.
• 🚗 Take a short test drive; you may notice smoother acceleration and slightly better throttle response.
• 📅 Plan to check or replace the engine air filter regularly (often every 20,000–30,000 km, or sooner in dusty conditions like many parts of Haryana).
