Screamin' Eagle 64MM EFI Intake Manifold

The Harley-Davidson Screamin' Eagle Extreme Flow 64MM EFI Intake Manifold is engineered to enhance the performance of Milwaukee-Eight powertrains that have been upgraded with Stage IV kits. Constructed with a cast aluminum body and CNC ported intake runners, this manifold ensures a smooth and uninterrupted flow of air, which is crucial for achieving maximum power output. Users can expect a performance gain of 2% to 4% in horsepower, contributing to a more responsive throttle. However, it is important to note that all applicable models require an ECM calibration using the Screamin' Eagle Pro Street Tuner or a dealership-installed Screamin' Eagle calibration to ensure proper function. The product is also 50-State U.S. EPA compliant. Fitment is specific: this manifold fits '18-later Softail models and '17-later Touring models. Crucially, it is not compatible with Center Cooled models. Additionally, specific exclusions apply to certain high-performance trims, including '23-later FLHXSE, FLTRXSE, '24-later FLHX and FLTRX, and '25-later FLTRXRRSE models. Pending approval for use in California on '21 models is also noted.
