Using these NGK V-Power spark plugs is easy. First, make sure your vehicle is turned off and has cooled down. Locate the spark plug wires and carefully remove them. Then, use a proper spark plug socket to remove the old spark plugs. Before installing the new ones, check the gap to ensure it's at the specified .043' (1.1mm). Gently thread the new spark plugs into the engine by hand to avoid cross - threading. Then, use the socket to tighten them according to the torque specs: 18 - 25.3 lb. ft. for cast iron engines and 18 - 21.6 lb. ft. for aluminum engines. Finally, reattach the spark plug wires.Note: Always follow the torque specs to prevent damage to the spark plugs or the engine. Don't overtighten. Also, make sure to buy from authorized dealers like Import Image Racing to get authentic products and the manufacturer warranty.For maintenance, it's a good idea to check the spark plugs regularly. Around every 15k miles, you can inspect them for signs of wear, corrosion, or fouling. If you notice any issues, it might be time to replace them. Keep them clean and dry when not in use.
