S&B Filters Turbo Inlet Manifold

The S&B turbo inlet manifold is a replacement for the restrictive factory mouthpiece that feeds the turbo on your LLY Duramax. The factory part reduces down to an extremely restrictive diameter which hinders airflow. The S&B manifold increases airflow by up to 78% over the stock manifold as well. Features a threaded port for pcv rerouting as well as a plug for those who have deleted their ccv system for race applications.
