The Grimmspeed 3-Port Electronic Boost Solenoid has been a treasure to the turbocharged world of sport compact drivers. one of their best selling items here at RallySport Direct is their easy to use 3-port Electronic Boost Control Solenoid. This particular boost control solenoid will allow the use 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. 

Grimmspeed also made it a point to use ultra-low profile hose fittings to keep the unit as small and compact as possible. The hose fittings are made of nickel plated brass so you don't have to worry about breaking the factory plastic hose fittings.
