{"product_id":"viton-integral-intake-valve-stem-seals","title":"Viton Integral Intake Valve Stem Seals","description":"The Supertech Viton Integral Intake Valve Stem Seals represent a critical maintenance upgrade designed to replace worn factory components in BMW and Mini B48 engines. By utilizing high-grade Viton material, these seals offer enhanced heat resistance and structural longevity, which directly addresses common issues such as increased oil consumption, excessive startup smoke, and diminished engine responsiveness that occur as original seals degrade over time.\n\nEach set contains 8 intake valve stem seals specifically shaped for the B48 engine family, ensuring a precise, leak-free fitment. Beyond restoring factory-level performance, these seals help maintain consistent combustion conditions and reduce emissions, making them a standard choice for both routine engine maintenance and performance-focused rebuilds. While compatible across the B48 engine platform, installers should note that these seals are integral components of the valvetrain and proper installation is required to ensure optimal sealing efficiency.","brand":"Supertech","offers":[{"title":"Default Title","offer_id":52663923573048,"sku":"SPTVSI-BM50-I-8","price":16.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687720606.png?v=1784330875","url":"https:\/\/store.motormia.co\/products\/viton-integral-intake-valve-stem-seals","provider":"MOTORMIA","version":"1.0","type":"link"}
