Billet Aluminium 4 Barrel 1375cfm Throttle Body Natural Finish Suit 4150/4500

Experience precision airflow with Aeroflow’s Billet Aluminium 4 Barrel 1375 CFM Throttle Body. Finished in a natural billet look, this unit pairs high-flow capability with rugged CNC machining to stand up to demanding conditions.

• 1375 CFM capacity for high-flow 4-barrel performance
• True CNC machined billet aluminium construction for durability and consistent dimensions
• Natural finish for a clean, aftermarket-ready appearance
• Dual-pattern flange to accommodate 4150 and 4500 carburettors
• Integrated idle air control valve (IAC) and throttle position sensor (TPS) for stable idle and precise throttle response
• 1.75" bore with a radius designed to minimize turbulence and maximize smooth airflow

Why it matters: With a true billet build and high-flow 1375 CFM rating, this throttle body helps your engine breathe more efficiently across RPMs, promoting stronger throttle response and steadier idle in street and strip scenarios. The dual-pattern flange eliminates the need for multiple upgrade parts, and the integrated IAC/TPS keeps idle quality consistent as temperatures and loads change.

Designed for 4-barrel applications, it’s an ideal upgrade when moving to 4150/4500 style carburettors or when you want a purpose-built performance throttle body that maintains precision at higher RPMs.
