Replacement intervals vary. Consult your vehicle's owner's manual for recommended intervals. Generally, spark plugs should be replaced every 30,000 to 100,000 miles, depending on the engine and spark plug type.

You will need a spark plug socket, a ratchet, a torque wrench, and a gapping tool.

No, ensure the spark plug is compatible with your engine model. Check your vehicle's owner's manual or the NGK website for compatibility information.

The correct torque specifications can be found in your vehicle's owner's manual or by consulting a repair manual.
