{"product_id":"30-00mm-inconel-751-alloy-exhaust-valve","title":"30.00mm INCONEL 751 ALLOY Exhaust Valve","description":"The Tomei TA303E-TY03A is a high-performance exhaust valve specifically engineered for the Toyota 2JZ engine found in the Supra JZA80 chassis. This EX valve features a 30.00mm diameter and a +1.0mm margin, with a head diameter of 99.10mm and a thickness of 5.97mm. It is constructed from INCONEL 751 ALLOY, a nickel-based heat-resistant material capable of withstanding extreme temperatures up to approximately 1000℃. This makes it ideal for high power applications where engine heat is a significant factor.\n\nThe oversized head diameter is application-specific to significantly improve flow rates, while the waisted stem design allows for greater volume of air\/gases to enter and exit the combustion chamber. These valves are precision machined with optimized head, face, stem, and lock groove designs to enhance sealing performance, efficiency, and overall durability.\n\nThis specific valve is intended as a repair part and can be purchased individually or as part of a complete intake and exhaust set. Proper installation by experienced, qualified mechanics using specialized tools is recommended, as with most performance engine components. Tomei Powered USA Inc. advises that some products may not be legal for use on public roads and that buyers should check local regulations.","brand":"Tomei","offers":[{"title":"Default Title","offer_id":52873033089336,"sku":"TA303E-TY03A","price":31.5,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/30-00mm-inconel-751-alloy-exhaust-valve","provider":"MOTORMIA","version":"1.0","type":"link"}
