This assembly is a collection of aftermarket components designed to replace or upgrade the factory air ducting system responsible for transferring cooled, compressed air from the intercooler to the engine on a 6.7-liter Powerstroke diesel engine. These kits typically include metal tubing, silicone couplers, and clamps, offering a more robust and efficient alternative to the original equipment manufacturer (OEM) parts. A common application is for those seeking enhanced performance and durability in demanding conditions.
The significance of upgrading this system lies in its ability to improve airflow, reduce pressure drop, and withstand higher boost pressures. The OEM piping can be prone to failure under increased stress, especially in modified engines. An enhanced kit contributes to improved throttle response, increased horsepower and torque, and a reduction in exhaust gas temperatures (EGTs). The development of these kits has paralleled the increasing popularity of performance modifications in diesel trucks.
