91mm Ported Throttle Body

The Soler Performance SE-KR3E-91NE is a premium, ported 91mm throttle body engineered to upgrade the stock unit in 2019-2023 Ford Mustang Bullitt and Mach 1 models. Vehicle manufacturers typically design throttle bodies for general use, but Soler Performance modifies the factory component to deliver superior airflow, quicker throttle response, and enhanced power, particularly beneficial for enthusiasts seeking a more spirited driving experience. This upgraded throttle body features optimized active contours with sonic flow nozzles to improve air velocity and volume. Its design includes a porting taper and upstream bore with a velocity stack for reduced lip and bore, further optimizing airflow efficiency. The unit boasts a 16 Ra microinch diamond-polished surface finish, which minimizes surface friction for smoother air passage. The shaftless design on the high-pressure side significantly increases the wide-open throttle flow area to an effective 91mm bore, boosting overall power. A self-cleaning throat and flow gap are incorporated for long-term reliability and consistent performance. Key benefits include immediate throttle response, a linearization and smoothing of the power curve for predictable response and crisper shifts, and increased air/power at every throttle position after idle. Importantly, this modification does not require tuning and is warranty-safe, providing a 20% flow increase over OEM units. The unit is proven for the Mustang Bullitt and Mach 1 models.
