Soler Engineering Premium Modified Throttle Body - 103mm (2015 - 2017 Roush Mustang | 2015 - 2020 Shelby GT350) - SE-GR3Z-103
High-Flow 103mm Upgrade for Roush & GT350 Engines
The Soler Engineering SE-GR3Z-103 is a premium modified, ported, and calibrated 103mm throttle body engineered for serious airflow demands. Designed for 2015 - 2017 Roush Mustang 5.0L owners and all 2015 - 2020 Shelby GT350 5.2L applications, this unit supports high-horsepower NA and forced-induction builds that require GT350 or GM LT-series throttle body bolt patterns.
Each assembly is sensor-matched and calibrated to eliminate the common drivability issues typically seen with oversize throttle bodies. Expect smooth idle, instant pedal response, and stable airflow throughout the entire RPM range - even with large cams, big blowers, or aggressive tuning.

FAQs
Does this fit a stock Roush or GT350 intake manifold?
Only if the manifold supports GT350 or GM LT-series throttle body patterns. Many applications require adapters or aftermarket manifolds.
Is tuning recommended after installation?
Yes. While some setups may function on stock logic, tuning is strongly recommended to optimize the added airflow.
