{"product_id":"crankcase-ventilation-check-valve","title":"Crankcase Ventilation Check Valve","description":"The ADD W1 Check Valve is engineered to enhance your vehicle's crankcase ventilation system by preventing backflow and stabilizing pressure. This patented component is essential for any oil catch can setup, offering crucial protection, especially for turbocharged or supercharged engines.\n\nThe product is available in two main options: Standard and PRO. The Standard Check Valve is designed exclusively for Naturally Aspirated (NA) engines and provides basic one-way airflow control. It is explicitly not compatible with turbo or supercharged systems. The PRO Check Valve is the recommended upgrade, required for Turbo \u0026amp; Supercharged engines, and supports high boost applications up to 100 PSI. It is also ideal for heavily modified performance builds and is compatible with NA engines for improved performance and reliability.\n\nEach kit includes one aluminum check valve (Standard or PRO) and two worm gear clamps, featuring durable anodized aluminum construction. The check valve can be installed on the outlet side of an oil catch can or inline with vacuum or boost lines to prevent reverse airflow. The valve opens in the forward direction at just 0.25 PSI and blocks pressure in reverse.\n\nCompatibility extends to ADD W1 catch cans (V1, V2, V3) and other aftermarket catch cans, making it ideal for turbocharged, supercharged, and modified engines. For any vehicle running boost, the PRO Check Valve upgrade is mandatory to prevent crankcase pressure issues and ensure long-term engine reliability.","brand":"ADD W1","offers":[{"title":"Default Title","offer_id":52872251277624,"sku":"ot-cv-9mm","price":13.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/crankcase-ventilation-check-valve","provider":"MOTORMIA","version":"1.0","type":"link"}
