S&B Turbo Inlet Manifold (2004-2005) - Chevy LLY

  • Sale

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.
