Description
A properly sized throttle body is critical for maximizing airflow and engine responsiveness in high-displacement engines. The S&S 66mm unit delivers significantly improved volumetric efficiency compared to undersized stock components, while maintaining full compatibility with your existing fuel system and sensors. This bolt-on upgrade requires no custom fabrication and preserves the factory appearance while unlocking measurable performance gains.
