Common Uses

• Restoring weak or inconsistent spark in high-mileage ignition systems
• Addressing rough idle caused by worn spark plug electrodes
• Replacing plugs at OE-recommended service intervals on Volvo, Subaru, Saab, Hyundai, and Land Rover models
• Helping correct misfire-related drivability concerns tied to plug wear
• Maintaining proper combustion in engines that specify iridium plugs with a 0.028-0.032 in. gap

Installation Notes

Verify the specified gap for your exact vehicle before installation, since listed applications vary between 0.028 in. and 0.032 in. Use the correct torque procedure for the cylinder head material and inspect ignition coils, boots, and wires during service. Confirm thread diameter, reach, seat type, and heat range match the engine specification before installing NGK 6481.
