The NGK V-Power spark plug is an OE-style nickel alloy plug featuring a V-cut center electrode and concave ground electrode to boost ignitability. That V-cut directs the spark toward the electrode edge for quicker starts and smoother idle, while the ceramic insulator and trivalent plating support dielectric performance and corrosion resistance. It’s a straightforward upgrade when improved starting and idle quality are desired over standard nickel plugs.
