NGK 7787 Spark Plug

NGK V-Power Spark Plug 7787 Overview

NGK V-Power Spark Plug 7787 is a copper-core, nickel-tipped spark plug built for stable ignition performance in a wide range of Toyota, BMW, Honda, Lexus, Saab, and other applications. It uses a 0.044 in pre-gap, a 5,000 ohm resistor, and a flat seat design to match OE-style service requirements.

The V-Power spark plug line focuses on consistent spark delivery and dependable operation across daily-driven vehicles. Part number 7787, also identified as LFR6C-11, is used in many late-model import applications where the specified gap and heat range matter for proper engine performance.

• Non-removable nut terminal

Detailed Product Description

NGK 7787 is an OE-style spark plug engineered around the specifications commonly required by Toyota Tacoma, Toyota Tundra, Toyota 4Runner, Toyota FJ Cruiser, BMW 328i, BMW X5, Honda Civic, and related vehicles. The copper core supports efficient heat transfer, while the nickel electrode materials help maintain consistent firing characteristics under normal service conditions. The 0.044 in gap and flat-seat configuration align with factory-style replacement needs for many applications.

This part cross-references BBB Industries 7787 for the same application. The NGK V-Power Spark Plug line is backed by NGK’s long history as a major OE supplier and manufacturer for domestic and import vehicles, with broad coverage across automotive, motorcycle, marine, and small engine applications.

Common Issues This Part Addresses

• Rough idle caused by worn spark plug electrodes
• Hard starting from weak or inconsistent spark output
• Misfire conditions related to incorrect plug gap or worn plugs
• Reduced throttle response from degraded ignition performance
• Service interval replacement for OE-specified spark plug maintenance

Installation Notes and Tips

Verify the vehicle application before installation and confirm the required gap for the specific engine. Some listed applications call for a 0.044 in gap, while Saab 9-3 fitment notes specify 0.040 in. Use care when handling the ceramic insulator and follow the manufacturer’s torque and service procedures for the engine.

For Toyota Tacoma, Toyota Tundra, and BMW applications, confirm the exact engine configuration and service specification before replacing the plugs. The part number 7787 and NGK LFR6C-11 reference the same spark plug design.
