The Wehrli Custom Fab 4" intake kit with air box is a high-flow replacement for 2006–2007 GM LBZ 6.6L Duramax trucks. The fabricated aluminum 4" piping and sealed air box draw cold air through the inner fender to increase airflow, improving horsepower, torque, throttle response and intake temperatures. Durable XLPE housing, stainless clamps, premium silicone coupling and a washable high-flow filter are included. The sealed housing uses the factory hood inlet and sight window for easy inspection. Bolt-on installation with basic hand tools; no tuning required.
