Audi A4/S4 B9 (2016 ->)

The Audi A4 is a line of luxury compact executive cars produced since 1994 by the German car manufacturer Audi, a subsidiary of the Volkswagen Group.

The A4 B9 is the fifth generation and is built from 2016 on a variant of the Audi Modular Longitudinal Platform, a platform that is also used in the Audi A5 coupé. The high equipped models have an adaptive suspension. The adaptive suspension system is implemented as a combination of ZF CDCI (continuous damping control internal) shock absorbers with coilsprings.

AirTec offers everything you need to keep your adaptive suspension running flawlessly.
