Product Description

The NGK 94712 Laser Iridium High Ignitability spark plug is an OE-style replacement plug designed for a wide range of Audi, Porsche, and Volkswagen turbocharged performance and passenger-vehicle applications. Also identified as SILFER8C7ES, it uses a fine-wire iridium center electrode and square platinum ground electrode to provide strong ignitability, consistent combustion, and extended electrode durability.

The plug features an M14 x 1.25 thread, 26.5 mm reach, flat seat, 16 mm hex, NGK heat range 8, and a 0.7 mm pre-gap. Its copper-core construction promotes heat transfer, while the alumina ceramic insulator provides thermal and electrical resistance. Trivalent metal plating helps resist corrosion and seizing, and the 1,000-ohm resistor helps reduce ignition-system electrical interference.

NGK 94712 is used across multiple engine families, including selected 2.0L I4, 2.5L I5, and 4.0L V8 applications. Because the same plug number can be specified for different engines and model generations, verify the exact vehicle, engine code, drivetrain, and OE spark-plug specification before installation. The product is sold individually.
