The DFC brake hose is a replacement line for 2018–2021 Subaru WRX STI (front left). It restores the hydraulic connection to the front left caliper to recover consistent brake fluid flow and pedal response after a damaged or worn hose. Verify the WRX STI model year and left front position to ensure proper fitment before installation.
