Racing Plug # 5962

The NGK Racing Plug # 5962 is a premium non-resistor spark plug engineered for high-performance and racing applications where maximum spark energy and throttle response are non-negotiable. Built for dedicated track cars, modified street machines, and serious engine builders, this NGK Racing Plug delivers the ignition consistency that separates winning builds from mediocre ones. Whether you're tuning a naturally aspirated engine for competition or optimizing a modified platform, the Racing Plug # 5962 is designed to handle elevated RPMs and aggressive fuel mapping without misfires.

This spark plug features a 14 mm thread size with a 0.749 inch reach and gasket seat design, ensuring proper seating in modern and vintage racing heads alike. The non-resistor construction eliminates the resistive element found in street plugs, allowing unfiltered spark energy to fire the combustion chamber—critical for maximizing ignition efficiency at high load and high RPM conditions. NGK's proven electrode geometry and premium ceramic insulator deliver superior heat range management, preventing fouling during extended full-throttle operation while maintaining plug life across multiple race seasons.

Mechanics, engine builders, and performance enthusiasts choose the Racing Plug # 5962 for carbureted and fuel-injected race engines, turbo applications, and high-compression builds. Installation is straightforward on any engine equipped with a 14 mm spark plug socket; verify thread pitch and reach compatibility with your cylinder head before ordering. The compact 0.95 x 0.85 x 3.35 inch profile fits tight engine bays without modification, and each plug ships individually for easy inventory management at the shop or track.
