Good To Know

Q: Is this manifold meant for low RPM driving? A: No, a single plane air gap manifold is built for higher RPM power, so it works best on performance builds rather than stock low RPM applications.

Q: Does the air gap feature matter on a big block? A: Yes, the air gap keeps the plenum separated from engine heat, which helps deliver a cooler, denser air and fuel charge.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
