Introducing the newest development from the Holley EFI engineering team. The Holley EFI High Flow Dual Port Boost Control Kit. 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. A black anodized billet aluminum manifold, with built in mounting provisions. Two pre-terminated connectors for a quick installation, and extra pins for those of you wanting to cut the harnesses to custom lengths. Finally two 1/4" push-lock fittings to simplifying the installation process. The Holley EFI boost control proprietary solenoid design flows nearly 40% more than comparable designs and up to 90% more than conventional 3-port boost control solenoids.
Features:
- Black Anodized Billet Dual Port Manifold
- Two 1/4" NPT Push-Lock Fittings for easy plumbing and installation
- Two Pre-Terminated connectors simply plug into the solenoids and pin into Holley EFI ECU connectors
- The billet manifold contains built in mounting provisions, setup for ¼ hardware
- Proprietary design to flows nearly 40% more than comparable designs and up to 90% more than conventional 3-port boost control solenoids

Note: When selecting solenoid configuration in the Holley EFI software, use the Dual Holley drop down selection. It is not advised to use the PWM+ outputs on an HP ECU, but rather use the PWM- Outputs. If you have a Dominator ECU, either use the PWM- outputs, or use a PWM+ output on the J2B connector.
WARNING: It is against the law to install this part on an Emissions Controlled Vehicle
