Anti-seize lubricates the thread, so the same wrench reading produces materially more clamp load. Shops that use it reduce the torque by roughly a quarter, and the figures here are that practice — BMW does not specify anti-seize on the plug thread and publishes no reduced value for it. Use one condition or the other; do not mix a dry torque with a lubricated thread.

This is the book's general row. In the book, pick your model and year and this figure resolves to your machine, with the one-page torque sheet, the job pages and the printable booklet.
