NGK 3194 Spark Plug

NGK BR9ES SOLID Spark Plug

NGK 3194 is a standard spark plug built for reliable ignition performance in a wide range of domestic and import engines. It uses a copper center electrode core, nickel center and ground electrode tips, and a 5,000 ohm resistor to support stable spark delivery and reduced electrical noise.

As part of NGK’s Standard Spark Plug line, this plug reflects the brand’s OE-focused approach to ignition components. NGK has long supplied original equipment spark plugs for North American vehicles, and the BR9ES SOLID follows that same emphasis on durability, consistent operation, and broad application coverage.

Key Features

• Part number 3194, also identified as BR9ES SOLID
• Standard spark plug design with a flat seat
• Copper center electrode core for dependable heat transfer
• Nickel center and ground electrode tip materials
• 5,000 ohm resistance for ignition system noise control
• Pre-gapped to .032 inch
• 14 mm thread diameter, .75 inch reach, 13/16 hex size
• Single ground electrode with standard configuration

Detailed Description

NGK 3194 is a conventional ignition service part for engines that call for a BR9ES SOLID spark plug specification. The copper core helps manage heat, while the nickel electrode construction supports consistent spark performance under normal operating conditions. With a flat seat, non-removable nut terminal, and manufacturer heat range 9, this plug is built to match the requirements of engines that specify this configuration. If you are searching for an NGK spark plug for motorcycle, marine, or small engine service, BR9ES SOLID is a direct reference point for those applications. It is also a relevant search term for Honda Civic ignition maintenance when comparing NGK 3194 against OE-style replacement options.

This part cross-references Anchor 3194 for the same application.

Common Issues This Part Can Address

• Hard starting caused by worn or fouled spark plugs
• Misfire from weak or inconsistent spark output
• Rough idle related to degraded ignition performance
• Reduced throttle response from aged plug electrodes
• Electrical interference concerns in ignition systems that require resistance

Installation Notes and Tips

Verify the engine calls for a 14 mm, .75 reach, flat-seat spark plug before installation. Check the gap against the engine specification, even though this plug is pre-gapped to .032 inch, and confirm the terminal style matches the ignition lead or coil connection. For Honda Civic, motorcycle, marine, or small engine service, compare the heat range and thread reach to the original plug specification before final installation.

Quality Assurance

NGK is a major OE spark plug supplier in North America and manufactures ignition components to original-equipment standards for durability and operational consistency. The BR9ES SOLID is backed by that OE-focused manufacturing approach and NGK’s long-standing experience in automotive, motorcycle, marine, and small engine ignition applications.
