Add Intake Porting: *

Want to take your LS3 Intake Manifold to the limit? Porting the Manifold also includes stand removal, and epoxying the manifold floor for maximum airflow!

*We don’t recommend this for forced induction setups, as removing the stands decreases the structural rigidity of the manifold.
