Description

Unleash your EcoBoost Mustang's hidden power with the SR Performance Throttle Body Spacer. This billet aluminum component is engineered to increase plenum volume, leading to improved low to mid-range torque specifically between 800 to 2500 RPM. The unique "Spiral Bore" design further enhances performance by spinning incoming air for improved atomization of the air-fuel mixture, which can also contribute to better fuel efficiency. It is designed as a direct fit for 2015-2023 EcoBoost Mustangs equipped with the turbocharged 2.3L Inline 4-cylinder engine and the factory throttle body. Importantly, this modification requires no tuning, simplifying the installation process. The installation is rated as simple, taking approximately 1 hour to complete. The package includes the throttle body spacer, a gasket, and four bolts.
