S&B Turbo Inlet Manifold For Chevy / GMC Duramax LLY 6.6L

The stock LLY turbo inlet is very restrictive, causing the turbo to over work and EGT's to go up. This causes dreaded thermal runaway. 

The S&B Turbo Inlet Manifold improves airflow to your engine by 78.6%, improves turbo spool, and lowers EGT's. Breathe Easy.
