Replaced my original boost solenoid that was worn out and not working with this one. Gained 1psi of boost and could definitely tell a difference! Well worth it if yours is really old or the stock one.

Took care of my DTC code read by FORScan, 99 7.3L has zero codes now!

Bough this since my 02 7.3 was frequently throwing an over/under boost code on CEL. Install was 5 minutes, biggest issue was getting the lines off the old one. Good price, quick delivery, works great.
Happy customer!

Didn't fix my issue, but not the solenoid's fault. Now it's on to checking wiring. The solenoid is great.

This was the first part I bought from Riffraff and before I bought from them I was a little hesitant. I had never bought from a performance part store and always did the same old big chain stores. After getting this part from them and seeing their customer services I will be buying everything else for my rebuild on my 7.3 from RiffRaff. My old part was completely fried, corroded, and very quiet when I tested it. I ordered this one and the shipping was handled very well and they provide an app where you can track this package. Once I got the part I tested it and it was very strong and full of life. install was very simple and I have had no problems with this code since thank you RiffRaff I look forward to more parts and I'm excited for this rebuild and having yall parts on my truck.
