24V Electronic Solenoid Valve for Cummins ISL & ISL9 8.9L Engines

High-Precision Turbo Actuator for Variable Geometry Turbochargers

This premium HE300VG / HE351VE electronic actuator is engineered to precisely control the VGT (Variable Geometry Turbo) system on Cummins ISL / ISL9 8.9L diesel engines.
If your vehicle suffers from power loss, turbo lag, check-engine lights, or actuator communication errors, this 24V electronic actuator is the ideal solution to restore optimal turbo performance.

Designed for heavy-duty commercial use, it delivers accurate vane control, improved throttle response, and enhanced engine efficiency under all load conditions.
