Performance valve springs feature higher spring rates reducing the chance of valve float and engine damage at higher RPM. Titanium retainers reduce mass allowing the valve train to rev higher, faster. The use of titanium provides an adequate fatigue life to be acceptable for all but the highest mileage street use. Supertech's 1.8T 20V spring kit is rated for use in engines up to 8000-8200rpm.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Details\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAll Supertech valve springs are made with premium Superclean Chrome Silicon Vanadium Steel alloy for higher performance \u0026amp; durability at high rpm. Using high-quality steel alloy also provides the added benefit of a better structural memory of the spring. The valve springs are computer designed to ensure that wire stress levels do not overpass the limits of stress defined in the diagrams of fatigue. This software also allows Supertech to ensure that the harmonics are under control, this advanced technology is combined with high-quality steel alloy making Supertech valve springs more durable in extreme conditions. Supertech valve springs give your performance street or race engine a serious competitive advantage in both performance and durability.\u003c\/p\u003e\n\u003cp\u003eSupertech retainers are manufactured with high-quality military grade Titanium alloy and CNC machined for an exacting fit.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eCompatibility\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eAudi B5 A4 1.8T 20V (1994-2001)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eAudi B6 A4\u003cspan\u003e \u003c\/span\u003e1.8T 20V (2000-2004)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eAudi 8L A3 1.8T 20V (1999-2003)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan mce-data-marked=\"1\"\u003eAudi 8N TT 1.8T 20V (1998-2006)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003eVolkswagen MK4 Golf 1.8T 20V (\u003cspan data-mce-fragment=\"1\"\u003e1998-2006\u003c\/span\u003e)\u003c\/li\u003e\n\u003cli\u003eVolkswagen MK4 Jetta 1.8T 20V (\u003cspan data-mce-fragment=\"1\"\u003e1998-2006\u003c\/span\u003e)\u003c\/li\u003e\n\u003cli\u003eVolkswagen B5 Passat 1.8T 20V (1996-2005)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003e\u003cspan\u003eST-SPRK-AUDI18\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eMore Information\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003e\u003cstrong\u003eManufactured by\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eSupertech\u003c\/span\u003e\u003c\/p\u003e","brand":"Supertech","offers":[{"title":"Default Title","offer_id":64545052295517,"sku":"ST-SPRK-AUDI18","price":783.46,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1069\/0009\/5325\/files\/SUPERTECHAUDIVOLKSWAGEN1.8T20VB5B68NMK4VALVESPRING_RETAINERSET_A4_TT_GOLF_PASSAT__01_a3dfab0a-9408-4124-9b8e-d9181a7b3c6a.jpg?v=1777364810","url":"https:\/\/performancepartsdirect.co.uk\/products\/supertech-audi-volkswagen-1-8t-20v-b5-b6-8n-mk4-valve-spring-retainer-set-a4-tt-golf-passat","provider":"Performance Parts Direct","version":"1.0","type":"link"}
