Introducing the newest development from the EFI engineering team. 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 in. push-lock fittings to simplifying the installation process. The 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.
