{"product_id":"inconel-exhaust-valve-set-1","title":"Inconel Exhaust Valve Set","description":"The Supertech Inconel exhaust valve set is engineered for demanding 1.8T 20V engine builds, offering a significant upgrade over stock components. The single groove valve keeper design provides a secure grip on the valve shaft, ensuring reliability even at high RPMs.\n\nThese valves serve as an excellent starting point for any 1.8T cylinder head rebuild, offering superior longevity and performance compared to OEM stainless steel or sodium-filled exhaust valves, which are prone to failure under extreme conditions. The Inconel material's resistance to heat minimizes the risk of valve damage, ensuring consistent performance. For those seeking maximum airflow potential, Supertech also offers these valves in a +1mm oversize option, which requires professional machining to achieve optimal flow characteristics.\n\nThis valve set is specifically designed to fit a range of Audi and Volkswagen 1.8T 20V models, including various B5 and B6 A4 chassis (1996-2005), TT Mk1 (1998-2007), Mk4 Golf\/GTI\/GLI (1999.5-2005), and Passat B5 (1998-2005) variants, covering both FWD and Quattro drivetrains. It's important to note that single groove valve keepers are required for installation and are available as a separate add-on. Additionally, a California Proposition 65 warning applies to this product, indicating potential exposure to chemicals known to cause cancer and reproductive harm.","brand":"Supertech","offers":[{"title":"Default Title","offer_id":52663923605816,"sku":"ST-AIVN-1103S \/ ST-AEVI-1103S","price":300.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687720615.jpg?v=1784330874","url":"https:\/\/store.motormia.co\/products\/inconel-exhaust-valve-set-1","provider":"MOTORMIA","version":"1.0","type":"link"}
