What This Spark Plug Helps Address

• Engine misfire caused by worn or fouled spark plugs
• Hard starting from weak ignition output
• Rough idle related to inconsistent spark delivery
• Reduced throttle response from degraded plug performance
• Maintenance replacement for Toyota Camry, Toyota Tundra, and Mitsubishi Eclipse ignition service

Installation Notes and Tips

Verify the engine calls for NGK 7990 / BKR6EYA before installation. Check and adjust the spark plug gap to the vehicle-specific specification listed in the fitment notes, including .044 inches for several Toyota passenger-car applications and .032 inches for several Toyota truck and SUV applications. Use the correct 5/8-inch spark plug socket and confirm the flat-seat design matches the cylinder head.

For best results, compare the removed plug’s part number, heat range, and terminal style before installation. Follow the service manual torque specification and inspect ignition wires or coils if the old plugs show signs of carbon tracking or heavy wear.
