🔧 Spark Plugs - Replacement

Your Rogue uses a 2.5L 4-cylinder engine with coil-on-plug ignition, so the spark plugs are under the ignition coils and intake ducting. This job is mostly careful disassembly, then proper plug gap and torque on reassembly.

Difficulty Level: Intermediate | Estimated Time: 1.5-2.5 hours

⚠️ Safety & Precautions

• Work on a cold engine only. Hot aluminum threads can be damaged easily.
• Disconnect the negative battery terminal before touching ignition coils.
• Keep dirt out of the spark plug wells. Debris can fall into the engine.
• Use only a spark plug socket with a rubber insert or magnetic grip.
• Do not over-tighten the new plugs. The cylinder head threads are aluminum.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the engine cover and intake duct

• Use your hands to lift off the engine cover if equipped.
• Use a flat-head screwdriver or 10mm socket to loosen the intake tube clamps.
• Remove any air duct fasteners with a trim clip tool if fitted.
• Set the intake duct aside so you can reach the ignition coils.

Step 2: Disconnect the battery

• Use a 10mm socket to remove the negative battery cable.
• Move the cable aside so it cannot spring back to the terminal.

Step 3: Remove the ignition coil connectors

• Press each coil electrical connector tab and pull the connector off by hand.
• If a connector is stuck, use a small flat-head screwdriver gently on the lock tab.
• Do not pull on the wires.

Step 4: Remove the ignition coils

• Use a 10mm socket to remove each coil retaining bolt.
• Twist each coil gently, then pull it straight out.
• Twist first, then lift.

Step 5: Clean the spark plug wells

• Use a shop vacuum to remove dirt around each plug well.
• If needed, blow out light debris carefully before removing the plugs.
• Keep all dirt out of the cylinders.

Step 6: Remove the old spark plugs

• Use a 3/8-inch spark plug socket, 6-inch extension, and ratchet to remove each plug.
• Turn slowly to avoid cross-threading or binding.
• Remove one plug at a time so you can inspect wear patterns.

Step 7: Check and install the new spark plugs

• Verify the plug gap matches specification before install.
• Thread each new plug in by hand first using the spark plug socket and extension.
• Once seated, tighten with a torque wrench to 18 Nm (13 ft-lbs).
• Hand-start every plug.

Step 8: Reinstall the ignition coils

• Push each coil straight down onto its spark plug.
• Install the coil bolts with a 10mm socket.
• Torque to 7.8 Nm (69 in-lbs).
• Reconnect each coil electrical connector until it clicks.

Step 9: Reassemble the intake system

• Reinstall the intake duct and tighten the clamps with a flat-head screwdriver or 10mm socket.
• Reinstall the engine cover by hand.
• Make sure all hoses and connectors are fully seated.

Step 10: Reconnect the battery and verify operation

• Reconnect the negative battery terminal using a 10mm socket.
• Start the engine and let it idle.
• Listen for misfires, rough idle, or check engine lights.

✅ After Repair

• Test drive the Rogue for smooth acceleration and idle.
• If the check engine light is on, scan for misfire codes.
• If you used anti-seize, make sure you did not over-apply it. Use a tiny amount only if needed.
• Recheck all coil connectors and intake clamps after the first drive.
