The factory specification for the electrode gap is 0.9 mm.
While NGK plugs are often close to the specified gap, it is industry best practice to always verify and adjust the gap manually to your vehicle's specific requirements before installation.
This plug is designed for standard daily-driver applications. High-performance engines often require specific heat ranges or precious metal electrodes like iridium or platinum.
The NGK 5165 is sold individually as a single unit.
You will need a 16 mm spark plug socket, a ratchet, and a torque wrench to ensure proper installation.
Verify the spark plug wire or ignition coil is fully seated on the fixed SAE connector and ensure the electrode gap was set correctly before installation.
Check that the plug is tightened to the correct torque specification to ensure a proper ground path through the gasket seat.
Proper installation is critical to the performance of any spark plug. When installing the NGK 5165, ensure the engine is completely cool to prevent thread damage to the cylinder head.
Regularly inspect the plugs during your scheduled maintenance intervals to check for carbon buildup, oil fouling, or erosion to ensure your ignition system remains healthy.
