We offer the Link 3 and 4 port boost solenoids for our customers to chose how they want to control the boost pressure of their build.

Which One Should You Use?

• For the best response and control, and if you need up to 3 times the boost than your wastegate spring is rated for, a 3-port is usually sufficient.
• If you need up to 4 times the boost your wastegate spring is rated for, a 4-port is a better choice.

Notes:

• Polarity does not matter when wiring a boost solenoid
