The new Big Sucker™ Stage 1 performance intake for Milwaukee-Eight® (M8) engines adds new features to the original industry leading air cleaner. The new patent-pending hidden breather system is o-ringed at the heads, passes through the backing plate and exits inside the mouth of the throttle body through proprietary shooter tubes

  • Increases Horsepower & Torque

  • Patent-pending hidden breather backing plate technology is a step up from our original patented system. Each breather is o-ringed at the heads, passes through the backing plate and exits inside the mouth of the throttle body through specially formed breather tubes
  • Eliminates oil blow-bye  issues associated with performance intakes on M8 engines 
  • Patent-pending oil catch is integrated into the backing plate and stops any excess breather oil from reaching the air filter. Oil catch is serviceable, simply bolt-on and off when your ready to wash/service the air filter 
  • Formed aluminum filter plate design with integrated mounting studs eliminates any internal mounting hardware 
  • Radius air inlet engineered to provide maximum airflow 
  • Outer filter lip covers the urethane on the base of the air filter for a clean look 

PERFORMANCE AIR FILTER:

  • Made from black pre-oiled cotton 
  • Engineered for optimum air flow and filtration. Perimeter flow design brings in air from all sides of the filter while filtering out all harmful debris 
  • Washable and re-useable, filter service kits are available 

AIR CLEANER COVER OPTIONS:
