S&S Cycle Premium 55mm CNC Ported Manifold For Harley Milwaukee-Eight

Knowing polished porting has little impact on the intake side, uniformly spaced and shaped texture is leveraged to encourage fuel dissipation, but also superior atomization of the fuel air mixture. Porting is done using a 5-Axis CNC for the ultimate consistent shape and flow characteristics.

Features:

• 5-Axis CNC ported
• Maximum aerodynamic efficiency
• Textured finish encourages fuel dissipation and atomization
• Works with stock and ported heads
• High-temp, durable black powder coat finish
• Made in the USA
