Engineered with high-quality iridium electrodes, these plugs deliver exceptional durability and consistent combustion efficiency, ensuring smoother engine operation across various driving conditions.

Yes, these plugs come with a factory-set 0.7 mm electrode gap, which is suitable for their intended applications.
While iridium plugs last longer than standard plugs, refer to your specific vehicle's maintenance schedule, typically between 30,000 and 60,000 miles depending on usage.
No, you must verify that your engine specifically calls for the OEM reference 06Q905601E.
You will need a 16 mm spark plug socket, a ratchet, and a torque wrench.
NGK generally advises against using anti-seize as these plugs have a special trivalent plating that prevents corrosion and seizing.
Verify that the ignition coils are fully seated and connected; check that the spark plug was tightened to the correct torque specification.
Remove the plug immediately and ensure the threads are clean; always hand-thread the plug for the first few turns to ensure alignment.
Before installing these spark plugs, ensure the engine is completely cool to avoid damaging the cylinder head threads. Use a 16 mm spark plug socket to remove the old plugs and install the new NGK 90781 units, being careful not to cross-thread them. It is recommended to use a torque wrench to tighten the plugs to the manufacturer's specific settings provided in your vehicle's service manual. These plugs are compatible with vehicles using OEM reference 06Q905601E. Keep the electrode clean of oil, carbon deposits, and debris during installation. Do not attempt to adjust the pre-set 0.7 mm gap, as iridium electrodes are brittle and can be easily damaged.
