TheGrimmspeed 3-Port Electronic Boost Solenoid has been designed to 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.
