{"product_id":"m156-m159-engine-oil-air-separator","title":"M156\/M159 Engine Oil\/Air Separator","description":"The Weistec Oil\/Air Separator system is a crucial upgrade for Mercedes-Benz vehicles equipped with the M156 or M159 engine, whether stock or modified with a Weistec Supercharger. This system actively reduces oil retention within the engine, thereby mitigating detonation and prolonging the life of internal components. By preventing aerated oil and particles from being drawn into the intake manifold through the PCV valve, it ensures a more stable and consistent power output.\n\nConstructed from CNC-machined 6061 aluminum with a hard anodized finish to military specifications, this oil\/air separator is built for durability and longevity. It features brass filter elements and is designed to be 100% serviceable. The installation is a direct bolt-in for M156\/M159 vehicles, offering flexible and reversible mounting options. The system accumulates oil in its lower body, which can be easily drained and recycled during routine oil changes.\n\nThis product is explicitly stated as direct bolt-in for M156\/M159 vehicles. Compatibility includes a wide range of Mercedes-Benz models such as the C63 AMG, E63 AMG, CL63 AMG, CLK63 AMG, CLS63 AMG, ML63 AMG, S63 AMG, SL63 AMG, and SLS AMG, across various model years from approximately 2007 through 2015, depending on the specific trim and engine configuration. Please consult the detailed fitment list for exact year, model, and engine compatibility.\n\nIt is important to note that this product may not be emissions compliant and users should check local laws prior to installation. Additionally, the product is not for sale or use in the state of California on any pollution-controlled vehicle, as per the California Air Resources Board. Some vehicles may experience more oil consumption or 'blow-by' than others; it is recommended to check the oil separator every 3,000 miles (5,000Km) if unsure.","brand":"Weistec","offers":[{"title":"Default Title","offer_id":52664118051128,"sku":"01-000-00383-5","price":500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687540392.jpg?v=1784333535","url":"https:\/\/store.motormia.co\/products\/m156-m159-engine-oil-air-separator","provider":"MOTORMIA","version":"1.0","type":"link"}
