Description

Banks' 3.5" boost tubes are the largest on the market, increasing airflow by 26-45% compared to stock. Made from aluminized steel with 5-ply silicone hoses and billet aluminum cold-side adapters, they reduce boost pressure loss, improve turbo spool, and increase power. The adapters feature a Venturi-like taper for optimal L5P airflow.
