Key Features of the Alloy Art Boom Box Air Cleaner Kit

Forward Offset Design for Airflow & Leg Clearance

• Forward Offset & Angled Filter: The unique forward offset design combined with a slanted, performance-style filter provides more airflow while improving leg clearance for taller riders.

• Optimized Comfort & Performance: Enjoy better ergonomics and enhanced airflow dynamics at every throttle twist.

Largest Side-Mounted Air Box & Filter Surface Area

• Unmatched Air Intake Capacity: The Boom Box features the largest side-mounted air box and filter surface area available for M8 motors.

• Maximum Breathing Efficiency: More surface area means more oxygen for combustion — translating into stronger acceleration and power output.

Max Volume Air Cleaner for M8 Motors

• Specifically designed for Milwaukee-Eight engines, this system ensures your motor receives the maximum air volume it can handle.

• Delivers a noticeable increase in torque, throttle response, and acceleration.

Oversized External Breathers

• High-Flow Breather Design: Oversized external breathers reduce internal crankcase pressure and improve overall engine efficiency.

• Ensures cleaner, unrestricted air movement throughout the intake system.

Internal Velocity Stack for Enhanced Performance

• The integrated velocity stack is designed to streamline airflow directly into the throttle body, minimizing turbulence.

• Promotes faster throttle response, smoother idle, and stronger top-end power.

Proudly Made in the USA
