Is your bike already equipped with a factory Stage I performance air cleaner? Raise the level another step! Zipper’s MaxFlow Stage I Upgrade Kit includes a specially designed, 100% washable pleated fabric filter made from multiple layers of surgical-quality cotton gauze material that traps the smallest dirt particles while providing dramatic flow increases. The element is 5/8” deeper than the factory performance filter it is designed to replace yielding over 60% more surface area than the Stage I filter. These kits are designed with the filter tapering outward towards the air filter cover, allowing use of 8” diameter EV-style round covers. Takes about 5 minutes to install – the difference is immediately noticeable!

MaxFlow Stage 1 Air Filter Upgrade Kit can be used on Evolution® or Twin Cam® engines if the appropriate EV-style cover is used. Specially designed 7” O.D. filter increases air flow while reducing intake turbulence. Includes air filter and required mounting hardware. 7” end diameter at cover mating surface.
