High Flow Boost Control Dual Solenoids

Introducing the newest development from the Holley EFI engineering team, our EFI high flow dual port boost control kit featuring two solenoids. This kit contains a set of pre-installed high flow solenoids, which feature a dual O-ring sealing design, preventing any boost leaks out of the manifold. The solenoids are driven by Pulse Width Modulated (PWM) outputs of the ECU.

Features:

  • Black anodized billet dual port manifold with built in mounting provisions
  • Two 1/4" NPT push-lock fittings for easy plumbing and installation
  • Two pre-terminated connectors simply plug into the solenoids and extra pins into Holley EFI ECU connectors
  • Proprietary design to flows nearly 40% more than comparable designs and up to 90% more than conventional 3-port boost control solenoids
