3.5-Inch Cold Side Intercooler Pipe Kit

The SPELAB Cold Side Intercooler Pipe Kit offers a robust upgrade for 2006-2010 6.6L LBZ and LMM Duramax diesel engines. This kit replaces the factory plastic cold side intercooler pipe with a heavy-duty, 3.5-inch diameter mandrel-bent aluminum pipe, designed to improve boost handling, durability, and airflow. Constructed from polished 6061 aluminum, the pipe ensures smooth airflow and superior heat resistance. It is paired with a triple-layer, reinforced silicone boot capable of withstanding high boost pressures and extreme engine bay temperatures. Included in the kit are two 3.5-inch cold side intercooler pipes, one silicone boot, two T-bolt clamps, and two 5/8-inch heater hoses, providing everything needed for installation. The product is compatible with stock turbochargers and intercoolers and explicitly states that no tuning is required, as it's designed as a direct OEM replacement. This intercooler pipe kit is specifically designed for 2006-2007 LBZ and 2007.5-2010 LMM 6.6L Duramax models. The manufacturer provides a 12-month warranty and a 30-day return policy for this product.
