Description
The NGK LFR5A-11 (Stock #6376) is a V-Power nickel spark plug designed to enhance ignition efficiency over standard plugs. Its V-groove center electrode directs the spark to the edge, improving flame kernel development for quicker starts, smoother idle, and better overall drivability. Built to OE specifications, it’s a dependable replacement for engines originally equipped with nickel plugs.
