The HSP LLY Intercooler Charge Pipe Bundle replaces the factory intercooler piping in your 2004.5-2005 GM 6.6L Duramax LLY. Included in the Intercooler Charge Pipe Bundle are 3” mandrel bent hot side and cold side tubes and a Y-bridge. The Intercooler Charge Pipe Bundle runs the hot side tube into the intercooler which results in improved clearance in tight places, better airflow, and lower temperatures. Featuring multiple color options, the Intercooler Charge Pipe Bundle is proudly made in the USA and includes 5 layer silicone boots.
