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.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eFeatures and Benefits\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e• Black anodized billet dual port manifold with built in mounting provisions\u003cbr\u003e• Two 1\/4” NPT push-lock fittings for easy plumbing and installation\u003cbr\u003e• Two pre-terminated connectors simply plug into the solenoids and extra pins into Holley EFI ECU connectors\u003cbr\u003e• Proprietary design to flows nearly 40% more than comparable designs and up to 90% more than conventional 3-port boost control solenoids\u003cbr\u003e\u003cbr\u003e\u003cem\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\/em\u003e","brand":"Holley EFI","offers":[{"title":"Default Title","offer_id":48275937657059,"sku":"557-201","price":878.7,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0660\/0821\/9875\/files\/f6d4b4c0288afbe844950b3200cbf80e.jpg?v=1771070263","url":"https:\/\/fastlanespares.co.nz\/products\/holley-557-201-efi-high-flow-dual-solenoid-boost-control-kit","provider":"Fast Lane Spares","version":"1.0","type":"link"}
