The SpeedFactory Racing 4-Port Boost Control Solenoid Kit allows precise boost control with a PWM (pulsewidth modulation) signal from a source (Engine Control Module or Electronic Boost Controller).

This solenoid can raise the boost level as high as 6-7 times the spring pressure of the wastegate and offers very precise control at very high boost levels.

The 4 Port Solenoid also allows you to use much lower wastegate spring pressures for better boost control when launching .

This kit can be used with single or multiple wastegates, and is compatible with almost every electronic boost controller and tuning software.

This product is for use with external wastegates only.

25Hz is our suggested starting point for control frequency in your EMS, and gives stable control in MOST setups. This is a maximum boost at 100% duty/normally closed solenoid. 4 port solenoids are more sensitive than 3 port solenoids and finding the correct control frequency to achieve stable boost control for your particular EMS and setup is part of proper boost control tuning. Improper control frequency will result in unstable boost control!

 

SpeedFactory 4-Port Boost Control Solenoid Kit Features Include:

-0-125 PSI pressure range

- (3) 1/8" NPT x 1/4" barbed male fittings and (1) sintered muffler

-24" wires leads for easy install

-Non-polarized wiring

-Compatible with Haltech, Motec, Hondata, Neptune, AEM, Megasquirt, Holley, KTuner, and many more!

Wonderful Room Partition !
Color: Black, Size: 88"- 4 Panel
This product is made very well, packaged, and assembled with no problems. All parts and tools are included (except a Phillips screwdriver.) I put this item all together by myself on a bed to make it easy and simple. I made sure that every screw head was attached where the recessed dimples are located on the vertical poles, just don't overtighten anything. Everything fits like a charm, good quality, looks great, perfect height, rolls with ease, proper privacy, really impressive ! I got the 4-panel in black color. I would certainly buy this item again ! Thank you !

Sturdy and Easy to Move
Color: Black, Size: 132"- 6 Panel
This 6 ft black partition on wheels is exactly what I needed to divide space without sacrificing style or stability. It’s sleek, professional-looking, and blends in well with any environment—from office spaces to home studios. The build quality is impressive—very sturdy and doesn’t wobble at all once it’s in place. The wheels glide smoothly and lock securely, making it easy to reposition or keep stationary as needed. Assembly was quick and straightforward, with all parts clearly labeled. Overall, this partition is a perfect combination of functionality and design. Highly recommend it if you need a durable, mobile room divider that looks great and performs even better.

Nice once put together.
Color: Black, Size: 88"- 4 Panel
I really enjoyed these ones. They got put up, putting them together was a two-man task and not very easy at all. They work really good. They're very heavy duty. You can hang things on them. I kick mine out of the way and they work like a charm!
