Direct-fit secondary air injection hose with a molded elbow design. Replaces cracked or aged air-system tubing on select 1.8L turbocharged applications.
$16.18
The 058 133 785B hose connects key components within the secondary air injection system on select 1.8L turbocharged applications. Its molded elbow design routes air between the air-pump pipe and check-valve pipe. This connection supports proper secondary air system operation during cold-start emissions control.
Heat cycles, vibration, and age can cause the original hose to harden, split, or lose its shape. Replacing a damaged hose restores the correct air path and helps prevent unmetered air issues.
The 058 133 785B hose helps the secondary air injection system deliver air through its intended route. A cracked or disconnected hose can disrupt system performance and may contribute to an illuminated check-engine light.
Replacing worn air-system tubing also helps maintain a clean, correctly routed engine-bay installation. Use a direct-fit replacement rather than adapting universal hose, as the molded shape must align correctly with the original connection points.
Inspect the air-system hose if you notice any of the following conditions:
Cracks, splits, or hardened sections in the hose material.
A loose connection at either end of the hose.
An illuminated check-engine light related to the secondary air system.
Audible air escaping near the hose connections.
A hose that has collapsed, distorted, or rubbed against nearby components.
OE Part Number: 058 133 785B
Function: Connects secondary-air-system piping and the check-valve connection.
Design: Molded elbow hose for OE-style routing.
Application: Select 1.8L turbocharged applications.
Fitment: Direct replacement design with no modifications required.
Service Benefit: Replaces aged or damaged secondary-air-system tubing.
Always verify fitment by VIN before ordering. Allow the engine to cool before beginning service. Inspect both connection points and adjacent air-system pipes for cracks, contamination, or damaged retaining hardware.
Install the hose without twisting or forcing the molded bends. Confirm that it seats fully at each connection and clears moving or high-temperature components. Inspect related secondary air injection components during the repair, including the check valve and air-system pipes.
Always verify fitment by VIN before ordering.
