📋 Before You Begin

• 🧰 Park on level ground, key off, and let the engine cool completely.
• 🧼 Put on safety glasses—you’ll be blowing debris away from the plug wells.
• 🧠 Quick terms: Coil-on-plug means each spark plug has its own ignition coil directly on top. Dielectric grease is a non-conductive grease that helps prevent moisture/corrosion on the rubber boot.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open access to the ignition coils

• Open the hood and locate the ignition coils on top of the engine.
• If anything blocks access (like an intake tube/cover), remove it using a 8mm socket and 3/8" drive ratchet.

Step 2: Unplug one coil at a time

• Work one cylinder at a time so nothing gets mixed up.
• Press the electrical connector lock and unplug the coil. If it’s stubborn, gently help the tab with a small flathead screwdriver (don’t break the plastic).

Step 3: Remove the ignition coil

• Remove the coil hold-down bolt using a 8mm socket and 3/8" drive ratchet.
• Twist the coil slightly, then pull it straight up to remove it.

Step 4: Clean the spark plug well

• Blow out the area around the spark plug using compressed air blow gun before loosening the plug.
• Tip: Keep the nozzle slightly above the hole.

Step 5: Remove the old spark plug

• Use a 5/8" spark plug socket, 3/8" drive extension, and 3/8" drive ratchet to loosen and remove the spark plug.
• If it feels extremely tight, stop and re-check that the engine is fully cool.

Step 6: Check and set the gap on the new spark plug

• Use a feeler gauge (spark plug gap gauge) to verify the gap matches the specification on the under-hood emissions label.
• If you must adjust, do it gently—do not pry hard on fine-wire iridium tips.

Step 7: Install the new spark plug (hand-thread first)

• Place the new plug in the 5/8" spark plug socket with a 3/8" drive extension.
• Thread it in by hand only (no ratchet) until it seats smoothly.
• Torque with a torque wrench: Torque to 15 Nm (11 ft-lbs).
• Tip: Don’t use anti-seize on plated plugs.

Step 8: Reinstall the ignition coil

• Put a small dab of dielectric grease inside the rubber coil boot (a pea-sized amount).
• Push the coil straight down until it fully seats on the plug.
• Install the coil bolt using a 8mm socket, then torque with a torque wrench: Torque to 7 Nm (62 in-lbs).
• Plug the connector back in until it clicks.

Step 9: Repeat for the remaining cylinders

• Repeat Steps 2–8 for the other three spark plugs.
• Reinstall any intake tube/cover removed earlier using a 8mm socket and 3/8" drive ratchet.

✅ After Repair

• 🧪 Start the engine and let it idle for 1-2 minutes. It should run smooth with no shaking.
• 🔍 If you get a check engine light or misfire, re-check each coil connector is fully clicked in and each coil is seated.
• 🚗 Take a short test drive and re-check for any new warning lights.
