HOLLEY EFI HIGH FLOW DUAL SOLENOID BOOST CONTROL KIT
PART # 557-201

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
