NGK 3722 Standard Spark Plug - BR5HS, Copper Core, Fits Chevrolet 60-69, Volkswagen 50-53/67-72
The NGK 3722 is a standard NGK spark plug built on the BR5HS design, an OE-cornerstone plug that has delivered decades of reliable performance in automotive and marine applications. Its solid copper core provides superior heat dissipation and conductivity across a broad heat range, helping the engine maintain consistent combustion and fuel economy. The plug is treated with a corrosion-resistant plating that keeps threads free of seizing, making installation and removal straightforward even after extended service. Construction uses a nickel ground electrode core, a copper center electrode core, and a nickel center electrode tip, a combination chosen for durability and stable spark performance rather than premium longevity claims. The plug has a standard ground configuration, a 13/16 inch hex size, and a preset gap of 0.024 inch. NGK 3722 is designed for applications including Chevrolet engines (60-69), John Deere 10-15, and Volkswagen engines (50-53, 67, 68-72). As with any spark plug, always check your engine and maintenance manual to confirm this is the correct plug and gap for your specific engine before installing, since using the wrong plug can reduce performance, reduce fuel economy, or damage the engine.
