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. A perfect combination for use with stock cylinder heads. Will work with any of the available intake elbow options.
On average we saw a 9cfm gain which is a 5% improvement.
The Z-Max Jr. gives improved volume over the stock intake in addition to Decreased EGT's
