KONI Special Active FSD Shock (Front) for 2017-2021 Audi A4/S4 AWD (49mm Clamp) 90 Part Number 1820258804 Part NameKONI Special Active shocks for the 2017 2021 Audi A4 AWD use KONI's patented Frequency Selective Damping (FSD) technology to deliver two damping curves in one fixed shock soft for low frequency road inputs (comfort) and firm for high frequency body motion (control). The result is a daily driver that feels composed without compromising ride quality. FSD reacts to the road, not to a driver setting, so there's nothing to adjust and nothing to wear out.
