{"product_id":"exhaust-valve-546","title":"Exhaust Valve","description":"The Tomei TA303E-SB04A is a high-flow, ultra-durable, heat-resistant race-spec exhaust valve engineered to withstand high power applications. It is meticulously designed and precision machined for specific engine fitment, with optimized head, face, stem, and lock groove designs to enhance sealing performance, efficiency, and durability.\n\nConstructed from a nickel-based heat-resistant alloy, INCONEL 751, this exhaust valve is built to endure extreme temperatures of up to around 1000℃. The valve features a waisted stem, which allows for a greater volume of air and gases to enter and exit the combustion chamber as the valve extends, though this feature may not be available on all models. The specific dimensions for this part are a head diameter of 30.00mm and a stem diameter of 5.45mm.\n\nThis exhaust valve is designed for the FA20DIT engine found in Subaru WRX models from 2015 onwards. It is part of a line of performance-oriented engine components from Tomei, known for their commitment to quality and performance enhancement. Professional installation by experienced mechanics is recommended due to the specialized nature of performance engine parts and potential requirements for specialized tools.","brand":"Tomei","offers":[{"title":"Default Title","offer_id":52873032925496,"sku":"TA303E-SB04A","price":31.5,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/exhaust-valve-546","provider":"MOTORMIA","version":"1.0","type":"link"}
