These problems may be caused by continuous oscillation of the boost valve within the boost sleeve, creating excessive wear and a path for EPC fluid pressure to leak to exhaust. Sonnax boost valve kit 104520-12K has upgraded materials and minimal clearances to prevent wear and restore proper hydraulic control. The sleeve also has a slightly larger EPC feed orifice to provide quicker throttle response. A new pressure regulator valve outer spring is also included to replace weakened original springs and provides a modest 5 psi increase across the pressure curve.\u003c\/p\u003e\n\n\u003cp\u003e \u003c\/p\u003e\n\n\u003cul\u003e\n\n\u003cli\u003eBoost sleeve is manufactured from highly wear-resistant billet aluminum to prevent wear\u003c\/li\u003e\n\n\u003cli\u003eLarger feed orifice provides quicker throttle response\u003c\/li\u003e\n\n\u003cli\u003eReplacement spring provides modest 5psi line pressure increase\u003c\/li\u003e\n\n\u003cli\u003eDrop-in Zip Valve™ parts install quickly and easily\u003c\/li\u003e\n\n\u003c\/ul\u003e\n\n\u003cp\u003e \u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e\u003clabel for=\"components-panel\"\u003eContents:\u003c\/label\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cdiv class=\"accordion-content\"\u003e\n\n\u003cul\u003e\n\n\u003cli\u003eValve\u003c\/li\u003e\n\n\u003cli\u003eSleeve\u003c\/li\u003e\n\n\u003cli\u003eSpring\u003c\/li\u003e\n\n\u003c\/ul\u003e\n\n\u003cp\u003e \u003c\/p\u003e\n\n\u003cdiv class=\"col-4\"\u003e\n\n\u003cp\u003e\u003cstrong\u003eSymptoms:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\n\u003cli\u003eLow line rise in Drive\u003c\/li\u003e\n\n\u003cli\u003eSoft shifts\u003c\/li\u003e\n\n\u003cli\u003eBurnt clutches\u003c\/li\u003e\n\n\u003c\/ul\u003e\n\n\u003cp\u003e \u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Suncoast Performance","offers":[{"title":"Default Title","offer_id":48219386413297,"sku":"104520-12K","price":47.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0641\/1344\/3057\/files\/Boost-Valve-Kit-Suncoast-Performance-151050542.jpg?v=1779828766","url":"https:\/\/tamelessperformance.com\/products\/suncoast-104520-12k-boost-valve-kit","provider":"TAMELESS PERFORMANCE","version":"1.0","type":"link"}
