• Specially designed "low profile " lid, base and filter system

• Helps reduce venturi effect across the carburetor to give more consistent air into the butterfly

• The lid and base have a female cavity that help align the filter with the male cavity to help gasket between them

• Any wedge nose cars like Modifieds and Late Models need to reduce the air coming across the top of the carburetor at yaw, this housing design is the solution

• Straight, clean air to the carburetor gives smooth acceleration off of the corner with no stumble due to air pressure differentials

• Walker recommends this filter housing setup for big tracks where aero plays more of a factor and air coming across the hood can be utilized

**Sure seal not included with base**
