The S&B Hot and Cold Side Boot Kit replaces the factory intercooler boots on the 2004.5-2005 Chevrolet / GMC Duramax 6.6L (LLY). Factory boots harden and split with age and heat cycling, and a blown boot dumps boost.
- Complete kit — all 4 intercooler boots plus a full set of 8 T-bolt clamps
- Covers both the hot side and the cold side in one part number
- Reinforced silicone rated for charge-air temperature and pressure
- Direct replacement for the OE boots — no cutting or fabrication
For the 2006-2010 LBZ and LMM, see part number 83-2019.
Confirm fitment for your exact year, model and configuration before ordering. Part number 83-2018.
