NGK 7654 Spark Plug

NGK Laser Platinum Spark Plug 7654

NGK Laser Platinum Spark Plug 7654 is a direct-fit ignition component built around a platinum center electrode, nickel ground electrode, and a 0.044 in pre-gap. It is engineered for vehicles that call for a flat-seat spark plug with a 14 mm thread diameter, 5/8 hex, and 26.5 mm reach.

As part of NGK’s Laser Platinum line, this plug combines OE-style construction with the brand’s long history as a major original equipment supplier. The PLFR6A-11 specification is used across select Toyota, Lexus, and Subaru applications, including Toyota Tundra, Tacoma, 4Runner, FJ Cruiser, Sequoia, Land Cruiser, and Lexus GX460 and LX570 coverage.

Key Features

• Platinum center electrode tip for stable ignition performance
• Copper core center electrode for efficient heat transfer
• Nickel ground electrode with standard tip and configuration
• 0.044 in pre-gap for listed applications
• 5000 ohm resistance
• Flat seat design with non-removable nut terminal
• NGK part number 7654 / PLFR6A-11

Product Details

This NGK spark plug is specified for engines that require the PLFR6A-11 design and matching heat range 6. It is a practical OE-style replacement for drivers searching for a Toyota Tundra spark plug, Toyota Tacoma spark plug, or Lexus GX460 spark plug with the correct thread, reach, and gap specification. The Laser Platinum construction supports consistent spark delivery in applications where factory-style fitment matters.

This part cross-references Bosch FR7MPP10 for the same application.

What It Helps Address

• Misfire caused by worn or fouled spark plugs
• Hard starting from weak ignition output
• Rough idle and inconsistent combustion
• Reduced throttle response from degraded plug performance
• Service replacement needs on listed Toyota, Lexus, and Subaru vehicles

Installation Notes

• Verify engine application before ordering; fitment varies by year and model.
• Adjust spark plug gap to 0.044 inches where noted in the fitment data.
• Confirm the flat-seat design, 14.00 mm thread diameter, 26.5 mm reach, and 5/8 hex match the original specification.
• Use the correct torque procedure for the cylinder head material and plug type.
