Larger Pipes. Less Restriction.
The factory intercooler pipes were designed to meet production costs—not maximize airflow, especially with an overall diameter of 2.75 inches. S&B replaces them with 3.5 inch diameter, mandrel-bent aluminum tubing that provides a smoother path for compressed air. The result is reduced restriction, improved airflow, and the performance your 6.7L Cummins deserves.
