Upgrading to performance spark plugs can significantly enhance the driving experience of your 2018 Acura ILX by improving combustion efficiency and throttle response. However, proper installation is crucial to maximize benefits and avoid potential engine issues. Everyday Acura shares essential tips to help you install performance spark plugs safely and effectively.

Preparation Before Installation

Start by gathering the right tools: a spark plug socket, a torque wrench, a gap gauge, and anti-seize compound. Make sure the engine is cool to prevent burns and avoid damaging the cylinder head threads. Consult your vehicle’s manual to confirm the correct spark plug gap and torque specifications for the 2018 Acura ILX.

Step-by-Step Installation Guide

  • Remove the engine cover to access the spark plugs.
  • Carefully disconnect the ignition coil connectors and remove the coils.
  • Use the spark plug socket to remove the old spark plugs by turning counterclockwise.
  • Check and adjust the gap on the new performance spark plugs as needed.
  • Apply a small amount of anti-seize compound on the spark plug threads to prevent seizing.
  • Install the new spark plugs by hand to avoid cross-threading, then tighten with a torque wrench to the recommended specification.
  • Reinstall the ignition coils and engine cover.

Final Checks and Maintenance

After installation, start the engine and listen for any irregular sounds. A smooth idle and improved acceleration indicate a successful upgrade. Regularly inspect your spark plugs as part of routine maintenance to keep your Acura ILX running at peak performance.
