The Harley-Davidson Screamin’ Eagle Heavy Breather Performance Air Cleaner Kit (Part # 29400227A) is a Stage I performance upgrade engineered to enhance both airflow and throttle responsiveness on compatible Sportster motorcycles. Designed as a direct enhancement over the stock or standard high-flow air cleaner, this kit combines functional performance gains with striking performance-inspired aesthetics that make a bold visual statement at the starting line or on the street.

At the heart of this kit is a forward-facing exposed element air cleaner system that draws a larger volume of air into the engine with less resistance than the stock intake. This optimized airflow can contribute to improved throttle response, better engine breathing, and a more responsive feel throughout the powerband — especially when paired with appropriate fuel management and tuning. (Harley-Davidson) Harley-Davidson Screamin’ Eagle Heavy Breather Performance Air Cleaner Kit 29400227AThe kit’s polished elbow and exposed filter element are designed to deliver both performance and eye-catching style. The washable and rechargeable filter features a bright chrome end cap adorned with a laser-engraved Screamin’ Eagle logo, emphasizing the performance pedigree of the component. The washable design also means riders can clean and reuse the filter element, reducing long-term maintenance costs and preserving peak performance over time. (Harley-Davidson)

Supporting the filter is an intake tube and backplate crafted from die-cast lightweight aluminum, which is polished and finished in gloss black for a striking contrast and a refined look that complements a variety of paint schemes and motorcycle finishes. The backplate also features integral breathers and a sealed breather bolt plug, helping maintain proper crankcase ventilation and clean styling.

Installation is straightforward and intended as a direct replacement for the stock air cleaner on ’14-later XL1200 Sportster models equipped with the Screamin’ Eagle High Flow 58 mm throttle body. However, because the heavy breather significantly alters the airflow characteristics of the engine, EFI-equipped models require ECM calibration for proper performance and drivability after installation. Models from ’17 onward typically need recalibration using the Screamin’ Eagle Pro Street Tuner or dealership-provided calibration.

The kit includes a water-repellent rain sock and all necessary mounting hardware, making it ready for installation right out of the box. Compliance with 50-State U.S. EPA emissions standards ensures legal street use when installed according to Harley-Davidson guidelines.
