Setup, Compatibility & Care Instructions
Setup:
- Ensure the engine is cool before beginning.
- Carefully remove the old spark plug using an appropriate spark plug socket.
- Verify that the NGK D6EA spark plug is the correct part for your vehicle's make, model, and year by consulting your vehicle's owner's manual or a parts catalog.
- Gently screw the new spark plug into the cylinder head by hand to avoid cross-threading.
