• Rough idle related to inconsistent spark delivery
• Reduced throttle response from degraded plug performance
• Service replacement for vehicles calling for NGK BCPR6ES-11 / 6779

Installation Notes and Tips

Verify the engine calls for NGK BCPR6ES-11 before installation. The listed pre-gap is 0.044 in, but several fitments note a 0.039 in gap or an OE-specified adjustment, so confirm the required gap for the exact vehicle and engine code before use. Check thread diameter, reach, seat type, and terminal style against the original plug to ensure proper fit.

For vehicles such as Honda Civic, Toyota Camry, and Nissan 300ZX, follow the service manual gap specification and torque procedure. Inspect ignition wires or coil-on-plug components during service so the new spark plug can perform as intended.
