Product Description

The Wilwood 221-17396 OEM Performance Flexline Kit is a vehicle-specific front brake hose upgrade for 2009-2016 Audi A4 B8 models. Wilwood catalogs this part specifically for the front brake system of the A4 and manufactures it as a one-piece assembly with the correct chassis and caliper fittings for the intended application.

Stainless-steel braided construction helps prevent compliance within the brake hydraulic system compared with conventional rubber hoses. This reduced expansion can provide a firmer pedal response and more consistent brake control. Wilwood further protects the Flexline with a clear anti-chafing coating designed to reduce exterior wear caused by contact with surrounding chassis and suspension components.

The 221-17396 covers the B8 Audi A4 through the 2016 model year and is applicable across the factory engine and drivetrain configurations cataloged for this generation where the front brake configuration matches. Because A4 models were offered with different engines, trims and FrontTrak or quattro drivetrains, the original front caliper and hose configuration should be verified before installation. After installation, inspect hose routing and clearance and bleed the brake system according to the applicable service procedure.
