thinking of building my own spacer same as the jdm one, but come on 100 is a little steap i might end up getting it if what i want to do doesnt work out.
heres the question, they say 16 HP? id have to see it to believe it but does the power come from the spacer being phenolic and cooling things better or does it come from the straighter airflow.
im thinking about making one out of aluminum but need to know.

 

It is a little of both

It keeps the upper intake cooler, and smooths out the airflow into the supercharger.
