Product Description
FLEECE FPE-34804 HE351 CW ACTUATOR SOLENOID PLUG WITH BOOST REFERENCE
The FLEECE FPE-34804 HE351CW Actuator Solenoid Plug with Boost Reference is the perfect solution when removing the factory electronic actuator on HE351-equipped 6.7L Cummins turbochargers. Designed by Fleece Performance Engineering, this billet plug seals the actuator port and provides a convenient 1/8” NPT boost reference port for wastegate control, data logging, or tuning-related boost pressure monitoring.
Whether you’re performing a turbo swap, converting to mechanical boost control, or simply need a reliable way to reference boost pressure, this plug ensures a leak-free seal and proper functionality while eliminating the electronic actuator entirely.
Key Features
- Replaces the factory HE351CW electronic actuator solenoid
- Provides a built-in 1/8” NPT boost reference port
- Ideal for mechanical wastegate setups and turbo swaps
- Billet aluminum construction for excellent sealing and durability
- Eliminates actuator-related boost leaks and failures
- Perfect for performance and tuning applications
Fitment
This Fleece actuator plug fits turbochargers equipped with the HE351CW actuator:
- 2003-2007 Dodge Ram 2500 5.9L Cummins (HE351CW turbo)
- 2007.5-2012 Dodge Ram 2500/3500 6.7L Cummins (HE351CW turbo)
- Any HE351CW turbocharger used in performance swap applications
Note: Not applicable to HE300VG VGT turbos used on later 6.7L Cummins unless converted to an HE351CW-style compressor housing.

Why This Plug Matters
The factory actuator on HE351CW turbos is a common failure point—especially on modified or high-mileage trucks. Removing the actuator is often required when installing:
- Aftermarket turbochargers
- Non-electronic wastegate systems
- Data logging equipment
- Standalone boost controllers
This Fleece plug keeps the turbo sealed while offering a clean, reliable boost reference to support tuning accuracy and mechanical boost control.

FAQ
Does this plug eliminate the factory HE351CW electronic actuator?
Yes. The FPE-34804 is designed specifically to replace the OEM actuator solenoid completely and seal the port.
What is the boost reference port used for?
The 1/8” NPT reference port can be used for mechanical wastegate control, boost gauges, data logging, or standalone tuning systems.
Will this work on HE300VG VGT turbochargers?
No. This is only for HE351CW turbochargers. VGT turbos require different components unless converted to HE351CW housings.
Does this part require tuning?
Tuning is not required for the plug itself, but depending on how the boost reference is used (wastegate control or logging), tuning may be recommended for optimal results.
Is this plug compatible with aftermarket turbo kits?
Yes. As long as the turbocharger uses an HE351CW-style actuator port, the plug will fit and function properly.
