6318455 NEW Cummins X15 EPA17+ Holset VGT Turbo Actuator

Please call us at 682-323-5959 to confirm current stock availability.

This brand-new Cummins X15 VGT turbo actuator is a genuine Holset variable geometry (VGT) electronic actuator for Cummins X15 engines running the HE400VG turbocharger. This is the newest-generation smart actuator, redesigned for the 8th-generation HE400VG series turbochargers, incorporating the latest chipset to enhance performance and durability. It is compatible with EPA17 and newer Cummins X15 engines and is supplied under primary part number 6318455.

When a Cummins X15 VGT turbo actuator fails, common symptoms include limp mode, low power, poor fuel economy, excessive smoke, turbo lag, and fault codes tied to VGT actuator position or boost pressure. Installing a new Cummins X15 VGT turbo actuator restores correct vane control without the expense of replacing the entire turbocharger.

Note: All VGT actuators must be calibrated to your turbocharger prior to operation using Cummins INSITE or another capable diagnostic tool. Calibration procedures may vary depending on the vehicle application and diagnostic tool used.

Includes a 1-year limited warranty — see our Warranty & Return Policy for full details.

Installation & Calibration Notes

The Cummins X15 VGT turbo actuator bolts directly to the turbocharger and connects to the OEM wiring harness. After mechanical installation, the actuator must be calibrated to the specific turbocharger using Cummins INSITE or a comparable diagnostic tool — an uncalibrated actuator will not correctly control vane position. Contact Vortex Turbo before ordering if you are unsure whether this actuator matches your turbocharger.
