{"product_id":"4-1-header-for-b16-b18-dohc-vtec","title":"4-1 Header for B16\/B18 DOHC VTEC","description":"The Yonaka Motorsports 4-1 ITR header is engineered for B16\/B18 DOHC VTEC engines, drawing inspiration from the JDM 1998+ Integra Type R B18C. It features 1 5\/8\" primary pipes that merge into a 2.5\" collector flange, aiming to increase horsepower and improve exhaust flow.\n\nConstructed from fully polished stainless steel, this header is designed as a direct replacement to enhance performance. It includes the necessary gasket for the connection to the cylinder head.\n\nImportant fitment notes apply: This header can only be installed on a B-series engine equipped with a DOHC VTEC oil pan and pickup. It will NOT clear AWD transmissions. Additionally, it is NOT compatible with non-VTEC heads or the B20A generation of Prelude engines.\n\nThis header requires a 2.5\" adapter flange, which is not included. It does not replace, alter, or remove emissions equipment and connects to the factory catalytic converter. However, it does not ship to California.","brand":"Yonaka","offers":[{"title":"Default Title","offer_id":52664154456376,"sku":"YONAKA-HEADERS-B16-EM1","price":229.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687543845.jpg?v=1784334247","url":"https:\/\/store.motormia.co\/products\/4-1-header-for-b16-b18-dohc-vtec","provider":"MOTORMIA","version":"1.0","type":"link"}
