SE4590-76NE 76mm Modified Throttle Body

The Soler Engineering SE4590-76NE Premium Modified Throttle Body is engineered to deliver sharper throttle response, higher airflow efficiency, and improved drivability for Cadillac's 3.0L twin-turbo V6 engines (LGW/LGY). This upgraded unit features a 76mm effective bore, achieved by porting a 72mm OEM base, which enhances midrange torque and off-idle response without requiring any tuning. Construction of the SE4590-76NE involves a refined port shaping and optimized active contours, leading to increased inlet velocity and minimized turbulence. The throttle body boasts a 16 Ra microinch ultra-smooth diamond-polished finish for smoother flow and higher discharge efficiency at the blade/plate interface. It also features a shaftless high-pressure blade side for increased Wide Open Throttle (WOT) area and thread-locked dome screws for long-term durability. This unit is built from brand-new OEM throttle body assemblies. The benefits of installing this throttle body include more spirited and agile part-throttle responsiveness, smoother throttle transitions, and immediate off-idle reaction with stable idle. It offers increased airflow and power potential across all throttle positions. The throttle body is a direct bolt-on, plug-and-play unit and does not require any tuning or an aftermarket Cold Air Intake (CAI). It is specifically designed for the LGW/LGY 3.0L twin-turbo platforms and improves throttle efficiency without affecting boost control or drivability. This throttle body is compatible with the following Cadillac models: CT6 (2016-2019) and CT5/CT5-V (2020-2025).
