Audi B5 S4 ECS Silicone Boost Hose Kit

The Audi B5 S4 requires a consistent, reliable supply of charged air to make usable power. In order to realize any performance gains from elevating the amount of boost, airflow routing must be smooth and resilient to the increased pressure demands.

ECS has undertaken the challenge of engineering a better flowing, more durable Silicone Boost Hose Kit for your B5.

A 4-ply silicone design with smoother bends results in greater airflow volume and more reliable boost delivery, ensuring manifold pressure always stays at peak levels to produce maximum power.
