Product Description

Factory boost tubes are one of the biggest restrictions in your intake system, especially once you start adding power. Smaller diameters and weaker materials mean more pressure loss and more work for your turbo just to hit the same boost levels. This Banks kit replaces both hot and cold side piping with full 3.5-inch constant diameter tubes, giving you up to 105% more flow where it actually matters. That means better boost retention, denser air, and more consistent power without pushing your system harder than it needs to.

Banks built this setup to handle real boost long-term. The aluminized steel tubes won’t crack like factory components, and the heavy-duty 5-ply silicone couplers with constant tension clamps keep everything locked in under pressure. Better airflow also helps bring EGTs down and improves overall efficiency, especially on tuned setups. Whether you’re running stock or planning to push more power later, this kit clears a major restriction and gives your engine the airflow it should’ve had from the start.
