The Cross Fire air cleaner designed is inspired by the Prodigy wheel found on Touring models. Each Cross Fire intake features a clear polycarbonate window, improved leg clearance & Patented performance features to take your motorcycle to the next level  

• Patented backing plate technology (US Patent: US 10,851,741 B1)
• Formed clear polycarbonate window 
• New reduced intake height for improved leg clearance 
• High performance black pre-oiled air filter 
• CNC machined from forged billet aluminum 
• Patented oil catch / reservoir 
• Increases horsepower, torque & mileage 
• Eliminates oil blow-bye on M8 engines 
• Finish: Black anodize 

FORGED BILLET ALUMINUM BACKING PLATE:

• CNC machined from forged billet aluminum 
• Features Patent-Pending next generation hidden breather technology. Each hidden breather is o-ringed at the heads, passes through the backing plate and exits inside the mouth of the throttle body through proprietary shooter tubes. This eliminates the need for any external hoses or hardware for a virtually closed loop system 
• Radius air inlet for unobstructed airflow
• Specially designed breather bolts are hidden under billet covers for a clean look 
• Eliminates oil blow-bye issues associated with M8 engines by directing any excess breather oil back into the engine 
• Patent-Pending Oil Catch / Reservoir. To ensure no oil saturates the filter and restricts your airflow, the integrated oil catch collects any excess engine oil before it reaches the air filter. Bolt-on design allows oil catch to be serviced when you service the filter element 

PERFORMANCE AIR FILTER:

• Black pre-oiled performance air filter 
• Designed for a clear polycarbonate top 
• Re-usable / washable filter 
• Rain socks / pre-filters and filter service kits available separately 

AIR FILTER HOUSING & CLEAR WINDOW 

• Outer air filter housing is CNC machined from forged billet aluminum 
• Clear Polycarbonate window allows you to view your engine's intake system in action
