GPI’s Rod Mod Intake program:
- We install radius bars to the LS3 manifold to help the air transition from the plenum to the runner.
- Dyno tested to gain about 5 rwhp on bolt on cars and around 12 rwhp on cammed setups.
- Porting the Manifold includes stand removal, and epoxying the manifold floor for maximum airflow (Optional).
This is the complete package to include porting and heat shield add-ons
