Description:

Elevate your Milwaukee-Eight (M8) engine’s performance with Ward Performance’s CNC porting service for the 64mm Screamin' Eagle intake manifold. With over 34 years of experience in motorcycle performance, Ward Performance delivers industry-leading results through precision-engineered upgrades.

Our CNC porting program utilizes advanced 5-axis CNC machining to optimize airflow, boosting the manifold’s performance from 376 CFM stock to 412 CFM after porting—a +36 CFM increase (a 9.6% improvement). This translates to a 6-8 horsepower gain, confirmed by back-to-back dyno testing. Beyond horsepower, this porting upgrade ensures compatibility with larger throttle bodies, larger injectors, and high-displacement builds. It is also a great option to pair with a turbo or other forced induction setups, offering unmatched flexibility for future performance upgrades.
