Give your Duramax engine the breath of fresh air it truly craves by swapping out restrictive stock parts for a massive 3-inch unobstructed flow path. This dynamic kit pairs the legendary SuperMax one-piece Y-bridge with a heavy-duty driver-side charge tube to drastically increase airflow and eliminate problematic factory couplers.

Precision TIG-welded tubing and robust CNC-machined flanges ensure seamless fitment without annoying fender rub. Complete with heavy-duty 5-ply silicone couplers and stainless T-bolt clamps, it delivers rock-solid boost handling and peak diesel performance.
