Big Sucker Air Cleaner Kit Stage 1

Stage I air filter kit is for fuel injected models.
The all in one backing plate features a built in carburetor support and built in breather tunnels at each head to decrease crankcase pressure. Each tunnel exits at the mouth of the carburetor to create a virtually closed loop system. Includes "Big Sucker" aluminum backing plate, high-flow air filter, 2 chrome banjo bolts, simple instructions, and all the necessary hardware. Bolt location, center to center, on Big Twin models is 15cm. *NOTE: Will not fit 2016-2017 FLSTB.
