This gives the actuator greater mechanical leverage against boost pressure and exhaust backpressure, while maintaining smooth and responsive operation across the RPM range.\u003c\/p\u003e \u003cp\u003eWith factory base pressure, this results in quicker spool, a stronger and more usable mid-range torque curve, and improved boost holding at higher RPM. Higher boost setups can further enhance performance, though ECU tuning and recalibration is recommended for best results.\u003c\/p\u003e \u003ch3\u003e⚙️ V-IWG Mk8 Fiesta ST FORD - 4inHg Features\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eProprietary Silicon Nomex Diaphragm\u003c\/li\u003e \u003cli\u003eHigh-Grade Billet Aluminium Construction\u003c\/li\u003e \u003cli\u003eStainless Steel Rods \u0026amp; Clevis\u003c\/li\u003e \u003cli\u003eTurbosmart Locking Collar System\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003e📌 Fitment\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eFord Fiesta ST Mk8 factory turbocharger\u003c\/li\u003e \u003cli\u003ePneumatic vacuum-operated OEM actuator replacement\u003c\/li\u003e \u003cli\u003eDirect bolt-on installation\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003e📌 Notes\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eDesigned for factory-frame turbo systems\u003c\/li\u003e \u003cli\u003eBest gains when paired with ECU tuning on increased boost\u003c\/li\u003e \u003cli\u003eImproves spool response, boost stability, and mid-range torque delivery\u003c\/li\u003e \u003c\/ul\u003e","brand":"Turbosmart","offers":[{"title":"Default Title","offer_id":56813690126641,"sku":"TS-0602-2046","price":248.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0906\/1787\/2689\/files\/15608.jpg?v=1792039510","url":"https:\/\/latemodelfordparts.com.au\/products\/turbosmart-v-iwg-mk8-fiesta-st-ford-4inhg","provider":"Late Model Ford Parts ","version":"1.0","type":"link"}
