AIRAID Throttle Body Spacer Ford Mustang 1999-2001 3.8L V6 - 400-594

AIRAID Throttle Body Spacer (Model: AIR-400-594)

The AIRAID Throttle Body Spacer is engineered to optimize your vehicle's performance by enhancing off-idle torque from 800 RPM to around 3,000 RPM. Its innovative, patented Helix Bore design creates a swirling motion in the incoming air charge as it travels through the spacer. This dynamic airflow not only increases the velocity of the air but also improves the atomization of the air/fuel mixture entering the combustion chamber, resulting in enhanced part-throttle torque and superior mid-range power delivery.
