MaxFlow Stage 1 Upgrade Kit for ’99-‘10 BT w/carb or cable Delphi® EFI equipped w/ factory Stage I A/C kit

Zipper's MaxFlow Stage 1 Upgrade Kit Twin Cam® w/Cables

Is your bike already equipped with a factory Stage I performance air cleaner? Raise the level another step! Our MaxFlow Stage 1 upgrade kit includes a specially designed, pleated fabric filter that is 5/8” deeper than the factory performance filter it is designed to replace. With more surface area, more airflow is achieved (9+%); more power is the result.

The kit includes our exclusive washable filter and mounting hardware, and takes about 5 minutes to install on engines equipped with throttle cables and factory performance filter # 29440-99D, 29773-02C (TC®) or # 29543-99B (EV). Accepts the standard TC "football" air cleaner cover (not included). Add one of our optional billet end covers for radical looks and performance!

Note - This kit is designed to be used on Twin Cam® engines equipped with H-D® Screamin’ Eagle® Stage I air cleaner and the standard Twin Cam® “football” cover, which makes 360º contact between the cover back and the rubber gasket on the filter. Do not install decorative cover inserts (due to increased weight) or use with 2006-up CVO Touring model oval covers that do not make 360º contact between the cover back and the rubber gasket.
