GrimmSpeed Boost Control Solenoid
Subaru Models (inc. 2008-2014 WRX / 05-09 Legacy GT)
Features & Product Details
RallySport Direct proudly carries a great selection of quality aftermarket performance products brought to you by GrimmSpeed.
This is the Grimmspeed 3-Port Electronic Boost Solenoid. This is one of their best-selling items here at RallySport Direct due to the simplicity of use along with the performance and reliability it provides. This particular boost control solenoid will allow the user to raise the OEM boost levels in a quick and efficient manner. Trying to raise the boost on the weak OEM solenoid can become unpredictable because of its inability to maintain proper and safe boost levels. By using the Grimmspeed unit you are able to improve boost response while maintaining a solid and consistent boost level. And it's also super durable as Griommspeed has crafted this solenoid to withstand 120psi which is much more than your engine will be able to see.
One of the greater aspects of this boost control solenoid is that Grimmspeed designed these to have model-specific brackets, as well as OEM connectors. This means that you can bolt the bracket right up to the factory solenoid provision and plug it right into the factory plug to be a direct fitment plug and play unit. this eliminates the need for wire splicing or using zip-ties that could potentially create a visual eyesore in the engine bay.

REVIEWS & CUSTOMER MEDIA
I installed this on my 07 LGT so if you have a wrx your mount may he slightly different but it's still just 1 nut to deal with. I followed the grimmspeed install video from their site which you can easily find on YouTube as well. Routing was quite simple, even for my ewg setup as they supply plenty of vacuum line for the job. I did however have an issue with fitting the line over the nipple on my wastegate but I had some spare silicone hose and clamps at home so I wouldn't even consider that a setback. DO NOT IGNORE THE HEEDS TO GET A TUNE AFTER INSTALL. I had my tuner fashion me one well before I my parts arrived in the mail.
Only ebcs ill buy. Easy to install based off the video on youtube directly from Grimmspeed.
I like this little thing. Wasn't too difficult to install, and I'm seeing fast but safe spool up on my ported VF52 turbo combined with the Grimmspeed topmount intercooler. Previously, when all I had was a cold air intake, downpipe, and stock topmount, my turbo would make its presence known by a steady whooshing noise. Now, I hear this awesome fluttering sound as I build boost. Almost sounds like a quieter version of an external wastegate. Datalogs show everything is working fine on the turbo. Great product, highly recommend!
Grimmspeed has never let me down, another quality part the functions perfect. Don't buy unless you're ready for a protune as you will overboost.
Bought this in conjunction with Cobb accessport, feels like a quality part and comes with everything youll need. install, with some really tight spaces and stubborn vacuum lines, took me about 2 hours. Overboost on any map is an understatement, NEED a proper tune with this mod. all in all another great grimmspeed part, worth the money for solid boost levels.

A: This would replace the manual boost controller. In theory you could run both but it is highly not recommended.
