Turbo Inlet Manifold for Chevy/GMC Duramax LLY 6.6L
Remove the huge restriction in your Duramax LLY 6.6L with the S&B Turbo Inlet Manifold, the highest flowing turbo mouthpiece on the market. Unlike the restrictive OEM turbo mouthpiece, which necks down and limits airflow, the S&B unit delivers an impressive 78.6% improvement in airflow. This reduction in restriction helps your turbo spool faster, lowers exhaust gas temperatures (EGTs), and reduces the risk of dreaded thermal runaway.
Built with high-quality construction, this turbo inlet manifold is crafted from cast aluminum with precise machined finishes, ensuring both durability and power gains for your LLY. For even better airflow, pair this manifold with an S&B intake, giving your Duramax engine optimal breathing room and performance. Get ready for improved throttle response, enhanced turbo efficiency, and more power when it’s needed most.
