The GMC Sierra 2500 HD Performance Air Intake - Wehrli - Stage 2 High Flow Bundle Kit - Gloss Black - ‘11-‘16 is a top-tier upgrade for your vehicle. This kit maximizes airflow to the engine, enhancing efficiency, throttle response, and turbo spool for the LML 6.6L Duramax engines.

This comprehensive package combines both the Stage 1 High Flow Bundle and Stage 2 Cold Air Intake Kit to replace restrictive OEM components. The transition from plastic to a fabricated aluminum intake and air box boosts engine power, eliminates weak points, and reduces failures. With large diameter 4" piping, smooth bends improve air velocity and cooler intake temperatures through cold air drawn via the inner fender. The 4.8 in. Cast Aluminum Turbo Intake Horn significantly enhances turbo spool and upper-end power, and new intercooler pipes are also included to optimize airflow and engine efficiency.
