Harley-Davidson Screamin’ Eagle Heavy Breather Elite Air Cleaner Kit 29400406

This Screamin’ Eagle Heavy Breather Elite picks up where the past generation Milwaukee-Eight Heavy Breather left off with a 15% air flow improvement! Redesigned to support even more performance with engine builds pushing over 135hp. The iconic Heavy Breather Air Cleaner features a forward-facing oiled cotton filter element that flows large volumes of clean air into the engine. The short, low profile cast tube rams the charge directly into the throttle body with little turbulence for increased power and torque, and the intake tube mounts to a custom back plate that features integral breathers and covers the throttle body electronics for a finished look. The slanted compact filter adds an aggressive performance look, and it is shaped to allow installation on Touring bikes equipped with fairing lowers.

At the heart of this kit is a forward-facing oiled cotton filter element that draws large volumes of clean air into the engine with minimal restriction. The design positions the filter to take full advantage of airflow dynamics, allowing the engine to breathe more efficiently than the stock intake. Complementing this is a short, low-profile cast intake tube that directs the air charge straight into the throttle body with minimal turbulence, promoting smoother airflow and enhanced throttle response.

One of the standout features of the Elite version is its precision-machined, forged aluminum cover. This not only adds durability and a premium look but also exposes as much of the filter media as possible to unrestricted air. The cover’s aggressive styling enhances the bike’s visual impact while serving a functional purpose — maximizing airflow where it matters most.

Fitment is broad but specific — it fits ’18-’24 Softail models and ’17-later Touring and Trike models, though some late model exceptions apply (for example, certain fairing lower configurations). Because this is a performance-oriented part, an ECM calibration (such as via the Screamin’ Eagle Pro Street Tuner or a dealer tune) is required to ensure proper fuel and air delivery and to fully realize the performance benefits.
