The GMC Sierra Performance Air Intake from Wehrli, known as the High Flow Bundle Kit Stage 1 in Flat Black, delivers a significant boost to your vehicle's performance. Designed specifically for the 2011-2016 LML Duramax models, this kit enhances airflow and efficiency.

This bundle addresses the inefficiencies and potential weak points of the factory intercooler pipes, offering reinforced strength and versatility. The kit increases the size of the passenger side intercooler pipe by 20% compared to the OEM part, eliminating the factory resonator and enhancing the aggressive sound of your turbo and engine. Constructed with robust 14 gauge aluminum and featuring upgraded silicone boots, this kit not only improves reliability but also mitigates horsepower-reducing boost leaks.
