Holley Systemax II Intake Manifold

(Requires adapter for use with 94-95 throttle bodies)

Holley says:
This Ford EFI passenger car manifold was developed by Holley for its SysteMax II Ford performance package. Don't be fooled by its California emission-legal designation. This manifold will flow like no other street/strip manifold. It's fully machined and ready to bolt down on any engine.
* 2000-6500 RPM power band
* Retains stock injector and water outlet locations
* External EGR passage maximized port and runner sizes
* Maximum unrestricted airflow
* Lower manifold parts match up to Holley cylinder head
* Special shiny finish

We say:
The SysteMax II intake manifold is the best we have ever tested to 6500 rpms for 302/331 c.i. natural aspirated combinations.
For forced induction the SysteMax II intake manifold with 302/347 c.i. combinations is one of the best if not the best up to 6700rpms.

SysteMax II intake manifolds is the most used intake in NMRA Pure Street and Renegade classes.
