The Clear Tear air cleaner series brings the timeless tear drop shape to a new level. Its smooth flowing cage like design is forged and features a domed shaped polycarbonate window that allows you to view the internal workings of your intake system while adding performance 

• Hard coated clear polycarbonate window 
• Domed / Radius shaped window is reversible 
• Patent-Pending hidden breather system 
• High performance black pre-oiled air filter 
• CNC machined from forged billet aluminum 
• Patent-Pending oil catch / reservoir 
• Increases horsepower, torque & mileage 
• Eliminates oil blow-bye on M8 engines 
• Red anodize finish 

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 

 Replacement Filter: 81-111

PERFORMANCE AIR FILTER:

• Black pre-oiled performance air filter 
• Tapered filter body designed to accept the clear polycarbonate top 
• Re-usable / washable filter 

AIR FILTER HOUSING & CLEAR WINDOW 

• Outer Teardrop is forged from aluminum and CNC machined to a cage like design  
• Clear Polycarbonate window is dome shaped, reversible design allows the window to be installed inwards or outwards 
• Polycarbonate is hard-coated for long lasting durability and protection from engine oil and UV sunlight
