{"product_id":"single-groove-intake-exhaust-valves","title":"Single Groove Intake \u0026 Exhaust Valves","description":"The Supertech Single Groove Intake \u0026amp; Exhaust Valves are precision-engineered components for BMW M50, M52, and M54 24v engines. Intake valves are crafted from an enhanced EV8 (21-4N) steel, chosen for its exceptional strength suitable for demanding applications. Exhaust valves utilize EV16 (21-8N) or EV8-Nb\/w materials, providing enhanced durability and strength under high-temperature conditions.\n\nThese valves feature a one-piece forged construction and are available with a black nitride coating. This coating provides a harder surface and smoother finish, which translates to reduced friction and increased longevity. Standard sizes include intake valves with a 33.00mm head diameter and 30.50mm head diameter for exhaust valves. Oversized +1mm options are also available for both intake and exhaust.\n\nIncluded with these valves are KPR-6S\/7 keepers. The product listing offers various configurations, including full sets of 12 intake and 12 exhaust valves, with options for standard or +1mm sizing, and Inconel material for specific exhaust valve applications.","brand":"Supertech","offers":[{"title":"Default Title","offer_id":52663920689464,"sku":"BMIVN-1030S - BMEVN-1030S 024","price":721.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687720484.jpg?v=1784330845","url":"https:\/\/store.motormia.co\/products\/single-groove-intake-exhaust-valves","provider":"MOTORMIA","version":"1.0","type":"link"}
