Description

The Pro Design Cool Head Shell is a CNC-machined billet aluminum cylinder head designed for Yamaha YFZ350 Banshee models from 1987-2006. This component utilizes interchangeable O-ringed domes to allow for precise compression adjustments based on fuel quality, elevation, or engine timing.

Built to replace the stock factory head, it provides substantial increases in engine cooling efficiency. The system is compatible with 19cc, 20cc, 21cc, and 22cc Pro Design cooling domes.
