Our plenums optimize airflow needed for engine cooling flow and reduced cooling drag. Cylinder head temperatures are closer to uniform and the overall cooling drag reduction can yield an increase in speed. Built from high-quality epoxy resin and fiberglass for quality you can trust.
This Engine Plenum is for the RV-4 with the 320 engine.
