NGK Laser Iridium Spark Plug ILFER7A8EG for Audi A7, Q5 PHEV, S3, and TTS and VW Arteon and Golf R (2017–2024)

For turbocharged Audi and Volkswagen models from 2017–2024, NGK 94726 is the Laser Iridium spark plug, designation ILFER7A8EG, built as an OE-equivalent design. A fine-wire iridium alloy center electrode carries the spark. Iridium is six times denser than platinum and has a very high melting point, which suits modern high-efficiency engines. A 98 percent pure copper core and a high-grade pure alumina ceramic insulator draw heat away from the tip to prevent overheating and to support reliable starts. Trivalent metal plating on the shell resists corrosion and seizing, which makes the plug easier to install and later remove. It corresponds to Audi and VW OE number 06K905601L.

This NGK spark plug carries a 24-month / 24,000-mile warranty.

NGK designs the Laser Iridium range for engines that come from the factory with fine-wire iridium plugs, and this one replaces that OE plug. Most Laser Iridium plugs add a platinum pad to the ground electrode for even wear in distributorless ignition systems, unless the OE specification calls for something else. The plug's job is to fire the compressed air-fuel charge in each cylinder, so the right heat range and electrode design matter on a turbocharged engine. To confirm a match, look for the ILFER7A8EG stamping or OE number 06K905601L on the plug you remove.
