    A:
    Before replacing the spark plugs, allow the engine to cool completely. Check the new plugs for defects and adjust the gaps as needed using a gap gauge. The gap should match the specification on the Emissions Control Information label. You can Select Your Vehicle to see complete installation and repair tips.
