{"product_id":"performance-single-groove-intake-valves","title":"Performance Single Groove Intake Valves","description":"The Supertech valve set includes 12 performance intake valves, serving as a strong starting point for any 1.8T 20V cylinder head build. These intake valves are engineered with single groove keepers, a design that enhances high RPM stability by securely gripping the valve shaft. This construction offers a more robust solution compared to traditional three-groove systems. The valves are crafted from an enhanced EV8 (21-4N) steel, chosen for its high grade and durability. They feature a Black Nitride coating, which provides a harder surface area and smoother finish, leading to reduced friction and extended lifespan. The set is offered with optional single groove valve keepers for added security in extreme applications. Specific dimensions include a 5.96mm stem diameter, 105.10mm length, and a 26.90mm standard head diameter. The product fits various Audi and Volkswagen models, including the A4 B5\/B6 (1996-2005) with 1.8T engines (FWD\/Quattro), TT Mk1 (1998-2007) with 1.8T engines (180HP\/225HP), Golf\/GTI Mk4 (1999.5-2005) with 1.8T engines, and Passat B5 (1998-2005) with 1.8T engines (4Motion\/FWD).","brand":"Supertech","offers":[{"title":"Default Title","offer_id":52663921672504,"sku":"AIVN-1103S 012","price":308.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687720482.jpg?v=1784330854","url":"https:\/\/store.motormia.co\/products\/performance-single-groove-intake-valves","provider":"MOTORMIA","version":"1.0","type":"link"}
