6.6L LLY Duramax EGR Delete Kit With High Flow Intake For 2004-2005 GMC Silverado

The 2004-2005 6.6L LLY Duramax EGR Delete Kit with High Flow Intake is designed to enhance engine performance by removing the Exhaust Gas Recirculation (EGR) system and replacing it with a high-flow intake.

• Every component undergoes rigorous leak testing, with O-ring seals ensuring a secure, leak-free installation.
