NGK LFR6A-11 V-Power spark plugs feature a V-shaped cut in the center electrode that helps direct the ignition spark to the electrode edge for improved spark development and increased ignition.
Check your engine owner's manual to find the correct spark plug and only use the spark plug as recommended by your engine's original equipment manufacturer (OEM). NGK's trivalent metal plating also provides superior corrosion protection in marine environments and prevents seizing for easier removal.
Don't just clean old spark plugs; replace them with new ones for better performance. Resistor-type plugs reduce fault noise transmitted to the vehicle's electronics.
