Description
If you’re running a Big Twin Harley and want to upgrade from a compliance-fitting or rigid-mount manifold, the S&S CYCLE manifold delivers the intake flow consistency needed for reliable performance across the RPM range. This CNC-engineered piece replaces decade-old OEM designs with precision engineering that supports both stock and performance cylinder heads. A straightforward bolt-on swap, it’s the foundation for building a modern intake system without fabrication headaches.
