Product Details

NGK’s Racing Spark Plug line is aimed at engines that operate at higher load, higher rpm, or in tuned conditions where consistent spark delivery matters. The B8EG uses a standard ground configuration with a single ground electrode and a copper core center electrode, a combination commonly selected for dependable ignition response and heat transfer characteristics. The flat seat, 14 mm thread diameter, and .75 reach make it a direct-spec spark plug for applications that call for these dimensions.

This NGK 3430 spark plug is a fitment-based choice for buyers comparing Honda Civic ignition parts or looking up B8EG cross-reference information for performance maintenance. This part cross-references Federal Parts (e.g., 2416) for the same application.

What It Is Used For

• Replacing worn spark plugs that cause rough idle
• Restoring ignition consistency in tuned or performance engines
• Addressing misfire conditions related to plug wear or gap drift
• Supporting cleaner combustion when the existing plug is fouled
• Maintaining reliable spark output in high-demand driving

Installation Notes and Tips

Verify the engine calls for a 14 mm, flat-seat spark plug with .75 reach before installation. Confirm the pre-gap against the vehicle’s ignition requirements and adjust only if needed. Use the removable nut terminal only when the ignition lead or coil connection requires it, and torque the plug to the engine manufacturer’s specification.

For Honda Civic applications and other vehicles that specify this format, match the heat range, thread diameter, and seat type exactly to the original equipment requirements. The NGK B8EG, part number 3430, should be installed on a cool engine to reduce the risk of thread damage.

Quality Assurance

NGK is a recognized ignition component manufacturer with a racing-focused spark plug line built around defined electrical and dimensional specifications. The B8EG is produced to the listed heat range, electrode materials, and terminal style for consistent part matching in performance ignition service.
