When to Change Your Spark Plugs
Spark plugs don’t last forever, here are some common signs indicating it's time for a change:
- Rough Idling or Misfires – If your engine stutters or idles roughly, worn-out spark plugs may be the culprit.
- Reduced Fuel Efficiency – A sudden drop in mileage often signals inefficient combustion caused by old spark plugs.
- Difficulty Starting the Engine – Faulty spark plugs can make starting your car harder than usual.
- Poor Acceleration & Performance – A sluggish response when pressing the accelerator could mean the plugs are no longer igniting fuel properly.
- Check If Engine Light On – Many modern vehicles will trigger a warning light when the spark plugs need attention.
Steps to Replace Spark Plugs
Replacing spark plugs is a straightforward process that can improve your vehicle’s performance. Here’s how to do it:
- Required Tools – You'll need new NGK spark plugs, a ratchet wrench with a spark plug socket, a gap gauge, dielectric grease, and an anti-seize compound (if recommended).
- Locate the Spark Plugs – Refer to your vehicle’s manual to find the spark plug locations.
- Disconnect the Ignition Coils/Wires – Carefully remove the ignition coil or spark plug wires without damaging them.
- Remove the Old Spark Plugs – Use the ratchet wrench with a spark plug socket to unscrew and remove each old plug.
- Check the Spark Plug Gap – Use a gap gauge to ensure the new NGK plugs have the correct gap as per manufacturer specifications.
- Install the New Spark Plugs – Thread the new plugs in by hand first to avoid cross-threading, then tighten them with the wrench (avoid over-tightening).
- Reconnect Ignition Coils/Wires – Securely reattach them to the new spark plugs.
- Start the Engine & Test – Turn on the vehicle to ensure smooth operation with no misfires.
Additional Important Spark Plug Information
- Heat Range Matters – NGK spark plugs come in different heat ranges; using the correct one prevents overheating or fouling.
- Regular Maintenance is Key – Even long-lasting iridium plugs should be checked periodically for wear.
- Torque Specifications Are Crucial – Over-tightening can damage the cylinder head, while under-tightening can cause misfires.
- Use Quality Fuel – Poor fuel quality can lead to faster spark plug wear and carbon buildup.
