Z-Max Jr. Ported Intake Manifold

The Z-Max Jr. partial ported intake manifold allows for even airflow to all cylinders. The intake passages are opened up by removing flow restrictions internal to intake manifold. Decreased EGT’s can be seen with the addition of the Z-Max Jr. A perfect combination for use with stock cylinder heads. Will work with any of the available intake elbow options.

We recently did some flowbench testing of the Z-Max Jr. intake manifold. We installed a cylinder head on a flow bench and then tested the stock intake manifold for flow. We then installed the Z-Max Jr. intake manifold and retested. On average we saw a 9cfm gain which is a 5% improvement. This testing does not account for the improved volume of area the Z-Max Jr. gives over the stock intake.
