The GMC Sierra Performance Air Intake - Wehrli - Stage 2 - Bengal Grey - '04-'05 is designed to optimize the performance of your GMC Sierra. It features an advanced air intake system that promotes improved engine performance by replacing the stock parts with high-quality aluminum components.

Dive deeper into what makes this performance part a must-have for your vehicle. This system is designed specifically for the '04-'05 Duramax LLY models, featuring a high flow aluminum intake pipe and an airbox enclosure with a dry filter assembly that significantly improves airflow. This increased airflow leads to better horsepower, torque, quicker throttle response, and cooler intake temperatures due to its effective cold air draw from the inner fender. It’s complete with large diameter 4" piping and aerodynamic bends that enhance air velocity and volume, resulting in a robust engine and turbo sound during acceleration. The package is crafted with high-quality components including a silicone boot, stainless steel t-bolt clamps and a 4.8 in cast aluminum turbo intake horn, which eliminates restrictions and offers compatibility with both OEM and upgraded turbos for enhanced turbo spool and top-end power.
