Our cold air intake for the 2004-2005 Chevy / GMC Duramax LLY 6.6L was engineered to minimize air restriction and flows 43.69% better than stock. This kit comes with a fully enclosed airbox that protects the filter from dirt and keeps out engine heat.
Our airbox provides an additional air intake in the bottom of the air box for maximum airflow. We also include a large silicone fender seal to keep the hot air out.
