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.\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBlack anodized billet dual port manifold with built in mounting provisions\u003c\/li\u003e\n\u003cli\u003eTwo 1\/4” NPT Push-Lock Fittings for easy plumbing and installation\u003c\/li\u003e\n\u003cli\u003eTwo pre-terminated connectors simply plug into the solenoids and extra pins into Holley EFI ECU connectors\u003c\/li\u003e\n\u003cli\u003eProprietary design to flows nearly 40% more than comparable designs and up to 90% more than conventional 3-port boost control solenoids\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Specifications:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Details:\u003c\/strong\u003e High Flow Boost Control Dual Solenoids\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade Type:\u003c\/strong\u003e Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet \/ Outlet Size:\u003c\/strong\u003e 1\/4\" NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Billet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Turbocharger Electronic Boost Controller\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Boost Control Part\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation Notes:\u003c\/h3\u003e\n\u003cp\u003eWhen selecting solenoid configuration in the Holley EFI software, use the Dual Holley drop down selection.\nIt 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.\u003c\/p\u003e","brand":"Holley EFI","offers":[{"title":"Default Title","offer_id":49715480821998,"sku":"HLY-557-201","price":478.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/9110\/6798\/files\/20ade1ece57ea8dac46c0c75f00f41cc053ad187.jpg?v=1791569154","url":"https:\/\/elmosspeedshop.com\/products\/holley-efi-high-flow-dual-solenoid-boost-control-kit-557-201","provider":"Elmo's Speed Shop","version":"1.0","type":"link"}
