103mm Throttle Body

The Soler Performance SE1000-103FORD is a premium, modified, ported, and calibrated 103mm throttle body engineered for high-performance engine modifications. This unit offers exceptional high flow capacity, rated at 1550 +/- 50 SCFM at 20” H2O at Wide Open Throttle (WOT). Key features include a porting taper and upstream bore with a velocity stack (lip and bore reduction), a 16 Ra Microinch diamond-polished surface finish for lower skin friction, and a dimpled pattern on the shaft's trailing edge. The body and sensors are calibrated as a matched set, ensuring no intrinsic calibration issues. This design contributes to a lower weight-to-power ratio at part throttle, a more nimble driving experience, and linearization/smoothing of the throttle curve for predictable response and crisper shifts. It provides more air and power at every throttle position after idle, and importantly, it does not introduce drivability, idle, or tuning issues commonly associated with similar-sized throttle bodies. This throttle body is compatible with 103mm+ aftermarket manifolds or superchargers that use the GT350 throttle body (TB) hole pattern or the GM LT1/LT2/LT4 TB hole pattern. Included with the throttle body are mounting screws and a gasket. An inlet coupler and transitional spacer are sold separately. This throttle body fits a range of Ford models, including the Raptor 6.2L (2010-2014), F-150 5.0L (2011-2021+), Mustang GT 5.0L (2011-2023), Roush (2015-2017), Shelby GT350 5.2L (2015-2020), and Mustang Mach 1 & Bullitt 5.0L (2018-2023).
