Unleash the Potential of Your LS Engine: Premium Aluminum Intake Manifold

Elevate your LS-powered build with Saifence® high-flow aluminum intake manifold. Engineered as a direct replacement and performance upgrade for popular cathedral port LS engines, this manifold is the key to unlocking improved throttle response, enhanced airflow, and reliable power. Whether you're replacing a worn-out factory unit or building a street beast, this manifold delivers exceptional value and performance.

Key Features & Benefits:

✔️ DIRECT BOLT-ON COMPATIBILITY: Specifically designed for easy installation on popular GM LS engines with cathedral port heads, including the LS1, LS2, and LS6. No complex modifications are needed for a perfect fit.
