Big Sucker™ Stage II air filter kit features a one-piece aluminum backing plate and carb support bracket with hidden breather technology.
Breather passages exit at the mouth of the carburetor or throttle body, creating a virtually closed-loop system that reduces external contamination.
This design eliminates the need for banjo fittings, hoses, and an external breather filter, simplifying installation and service.
The kit includes all necessary hardware and step-by-step instructions; the filter is washable and reusable for long-term maintenance.
Made in the USA and compatible with '93–'99 Evolution Big Twin models equipped with CV carburetors.
