Installation Notes and Tips

Verify the vehicle’s original hose routing, end styles, and connection diameters before installation. EMH222 is intended for the secondary air pump to pipe position on the listed Audi and Volkswagen models, so matching the molded shape and connector orientation is important for proper installation. Inspect adjoining pipes and connectors for wear or damage before replacing the hose.
