This 3.5″ Intercooler Pipes & Intake Manifold Kit upgrades your Cummins charge air system with 3.5'' mandrel-bent aluminum charge pipes, a high-flow intake elbow, reinforced silicone boots, and heavy-duty spring clamps for maximum reliability and airflow efficiency. Not CARB Compliant, for off-road and competition use only.
Fitment
- 2003 - 2007 Dodge Ram 2500 / 3500 5.9L Cummins Diesel
Product Features & Benefits
✔ Upgraded 3.5″ High-Flow Tubing
Our intercooler pipes are upgraded to 3.5-inch mandrel-bent aluminum tubing for smoother airflow. OE intercooler pipes are 3-inch design.
✔ High-Flow Intake Elbow Included
This kit includes a high-flow intake manifold elbow to replace the OE intake horn, which helps reduce turbo restriction and lower EGT under load.
✔ Constant-Tension Spring Clamps
This kit includes stainless steel spring clamps that maintain constant pressure when temperatures fluctuate, providing blowout-resistant seal and reliability under high boost.
✔ Reinforced Silicone Boots
OE rubber boots become weak and brittle over time. We provide reinforced silicone boots in this kit for high boost pressure and extreme engine bay temperatures.
✔ Direct OEM-Style Fitment
This kit is precision-designed to fit factory mounting locations without custom fabrication.
✔ Lightweight Aluminum Construction
Manufactured from premium mandrel-bent aluminum with durable black finish for excellent corrosion resistance and long-term structural durability.

FAQs
Q: Does this kit include both hot and cold side intercooler pipes?
A: Yes. This is a complete kit with hot side pipe (from turbo to intercooler), cold side pipe (from intercooler to intake), and high-flow intake elbow.
Q: Do I need custom tuning?
A: No tuning is required. This is a direct-fit airflow upgrade that improves efficiency and lowers EGTs even on stock trucks. Tuned trucks will benefit even more from the increased airflow capacity.
Q: Why use spring clamps instead of T-bolt clamps?
A: Diesel engines experience significant heat expansion and contraction. Standard clamps might loosen over time, while constant-tension spring clamps maintain sealing pressure through all temperature cycles.
Q4: Will this fit a 6.7L Cummins?
A: No. This kit is specifically designed for 2003–2007 5.9L Cummins engines only.
Q: Is this CARB compliant?
A: No. This product is intended for off-road or competition use only, and is not CARB exempt.
