Our cold air intake for the 2003-2007 Dodge Ram Cummins 5.9L was engineered to minimize air restriction and flows 42% better than stock. This kit comes with a fully enclosed airbox that protects the filter from dirt and keeps out engine heat. Silicone is a premium rubber which will seal better and last longer. It handles as much as 400F without cracking or tearing. With a high friction surface and no oily residue, our silicone filters and couplers won’t slide off the tube. The secondary inlet lowers the restriction level, resulting in better airflow and performance. Our one piece air box design features an integrated box seal that keeps out unwanted engine heat. The cooler the air, the greater the dessity, resulting in better performance.
