The newly integrated patent-pending oil catch makes sure no oil ever touches the massive perimeter-flow air filter.

Description

Patent-Pending Backing Plate:

  • Aluminum  
  • Patent-pending hidden breather technology is an enhanced version of our 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 acts as a reservoir by stopping any excess breather oil from ever reaching the air filter. Serviceable design, simply bolt-on and off to wash  
  • Formed radius air inlet engineered to provide unobstructed airflow 
  • Outer filter lip matches up with the factory air cleaner perfectly and covers the urethane on the base of the air filter for a clean look

Performance Air Filter:

  • Made from red 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 
  • Massive size, over 200% more filter surface area than the factory air filter. Features pleated material around the entire perimeter of the filter 
  • Washable and re-useable, filter service kits are available 

Filter Top Plate:

  • Aluminum  
  • Specially formed to secure the air filter and mount directly to the backing plate
  • The design eliminates any internal mounting hardware for increased durability 
  • Integrated air venturi directs air into the throttle body
