The S&S Cycle premium oval port manifold is carved from solid 6061-T6 billet aluminum using advanced 5-axis CNC machining and is specifically port-matched to integrate seamlessly with Screamin’ Eagle Stage IV CNC ported Gen 2 cylinder heads, maximizing airflow velocity and power on 2023 to present Touring and 2025 to present Softail. Designed for effortless installation, the kit retains your factory fuel rails or can accept S&S billet fuel rails and includes a premium manifold-to-throttle body o-ring for a perfect, leak-free seal. Choose between the 64mm or 68mm options to perfectly match your large-bore throttle body and unleash the absolute full potential of your M8 engine. The 64mm is a unique oval port manifold which is not offered by Screamin’ Eagle and intended to be used with the 64mm throttle body that is sold for Gen 1 Milwaukee Eights. The S&S 68mm Stealth kit has adapter for 64mm throttle body.
