The Koni Special Active FSD left front shock for 2014–2017 Mazda3 is a vehicle‑specific, twin‑tube hydraulic low‑pressure gas McPherson strut featuring Koni's Frequency Selective Damping (FSD) technology. Offered as a non‑adjustable replacement for the left front, it restores the intended strut function for McPherson suspension setups and is specified for use where factory fitment and ride characteristics are required.
