DHD 402-102 LLY Duramax Cold Side Intercooler Kit Aluminum
The DHD intercooler tube represents the next level air intake products for your Duramax Diesel. Our tubes outflow the factory intercooler tube by approximately 35%-40%. Our tubes are a 100% perfect fit and come complete with our heavy duty silicon couplers and stainless steel T-bolt clamps for a secure installation. Our pipes are assembled from 3" mandrel bent aluminum tubing for maximum flow and lite weight. Most aftermarket tubes are either steel which is heavy and not very corrosion resistant. All or our DHD intercooler tubes will have smooth transition bends that allow for low resistance airflow, increasing horsepower, torque and lowering EGTs!
