{"product_id":"black-nitride-valves-4g63","title":"Black Nitride Valves (4G63)","description":"The Supertech Black Nitride Valves are performance-grade components for 4G63 Evo, DSM, and GVR4 engines. Crafted from a single piece of forged stainless steel, these valves are treated with a special hardening process and a black nitride finish. This treatment reduces friction between the valve and its guide, which can lead to decreased power loss at higher engine speeds.\n\nThese valves are available in multiple sizes to precisely match your cylinder head diameter, with options for both intake and exhaust applications. Each type is offered individually or in sets of 8 for a complete engine overhaul. For a full replacement, you will need 8 intake and 8 exhaust valves.\n\nVehicle fitment includes: 1992-2006 Evolution I-IX, 1990-1999 Eclipse GST\/GSX, 1990-1998 Talon TSi, 1990-1994 Laser RS, and 1991-1992 Galant VR-4. It is crucial to conduct thorough research and consult with your engine builder to ensure proper selection and installation.","brand":"Supertech","offers":[{"title":"Default Title","offer_id":52664189452600,"sku":"MIVN-1007\/MEVN-1007","price":22.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/686853931.webp?v=1784334932","url":"https:\/\/store.motormia.co\/products\/black-nitride-valves-4g63","provider":"MOTORMIA","version":"1.0","type":"link"}
