Cowl and Plenum:

The average speed increase is 7-10 mph.  This is made possible through a substantial reduction in overall cooling drag.  This is accomplished through the use of a "sealed" plenum system and circular inlets.

With the sealed system, pressure losses are reduced and through careful control of airflow, a lesser volume of air is required for cooling.  Drag is reduced and cylinder head temperatures are uniform within a few degrees.

Induction Air:

Our system uses a very low restriction K&N filter and has provision for carburetor heat.  The system for forward facing injected engines provides an additional one inch of manifold pressure over ambient at 5000' density altitude.
