Mishimoto 2002-2004.5 Chevrolet/GMC 6.6L Duramax LB7 Intercooler Pipe and Boot Kit

Upgrade your 2002-2004.5 Chevrolet Silverado 2500HD/3500 or GMC Sierra 2500HD/3500 with the Mishimoto intercooler pipe and boot kit designed for the 6.6L Duramax LB7 diesel engine.

  • Premium Clamps: Includes T-bolt clamps and stainless steel constant tension clamps for secure, vibration-resistant connections
  • CNC-Machined Aluminum Fittings: Precision-machined for perfect OEM fitment and seamless integration with stock intercooler setup
  • Direct Bolt-On Design: No cutting, drilling or modifications required, installs in under 1 hour with basic tools

Product Notes
