GrimmSpeed offers the most complete and easy to use 3-Port Electronic Boost Solenoid available on the market. This boost controller allows you to raise boost levels in a quick and efficient manner. When raising boost using the weak OEM boost solenoid it will start to become unpredictable and unable to maintain proper and safe boost levels. The Grimmspeed 3-port Boost Control Solenoid enables quicker spool times and a rock solid boost level. This solenoid is so tough that GrimmSpeed has designed it to withstand 120 PSI, which is much higher than you will ever need!

ECU TUNING IS REQUIRED FOR THIS PRODUCT.

Key Features:

• Spool faster (10% more than other brands).
• Plug and play (OEM connector plugs in).
• Factory style bracket for perfect fit.
• Designed with correct coil impedance to work safely with factory ECUs.
• Nickle plated fittings will not break like cheaper plastic ones.
• Simple install and easy to tune.

Tuning Note: As with any boost controller, if used to raise boost significantly (more than 2-3 PSI) we strongly recommend a full ECU re-tune for best performance and engine life.
