Gain massive airflow to your Duramax for increased power, lower temperatures, and more MPG's with the installation of this cold air intake from Banks that takes full advantage of your factory ram air induction hood.
The factory air filter housing has little room for air to flow around the filter. The Banks Ram-Air housing has a larger inlet and ballistic-shaped nose, which encourage the reusable or dry air filter to freely inhale for more power.
