Spark plugs typically come pre-gapped for their intended application. However, it's always best practice to verify the gap before installation to ensure it matches your vehicle's specifications.

Ensure the spark plug is correctly installed and torqued. Check for proper gap (if applicable) and inspect the plug for fouling or damage. Verify compatibility with your vehicle.

A faulty spark plug can trigger a Check Engine Light. If misfires are detected, replace the spark plug and clear the code. If the issue persists, further diagnosis is needed.

Worn or fouled spark plugs can reduce efficiency. Replacing with new, correctly specified plugs like the NGK 5483 can help restore optimal combustion and fuel economy.
