Speedmaster 1-539-003 LS Throttle Body Adapter 102mm to 96mm 4-Bolt

The Speedmaster 1-539-003 is a precision-engineered throttle body adapter designed to connect a 102mm 4-bolt throttle body to a 96mm 4-bolt LS intake manifold. This adapter allows you to upgrade to a larger throttle body while maintaining compatibility with your stock or aftermarket LS intake.

Key Features:

• Aerospace-grade aluminum construction for strength and durability
• 102mm inlet to 96mm outlet configuration with tapered bore
• 4-bolt pattern on both sides for secure mounting
• Designed specifically for LS engine applications
• CNC-machined for precise fitment and optimal airflow
• Lightweight design minimizes added weight to intake system

This adapter plate enables performance enthusiasts to maximize airflow potential by stepping up to a larger throttle body without replacing the entire intake manifold. The tapered design ensures smooth air transition and minimizes turbulence for improved throttle response.
