{"product_id":"disa-valve-2","title":"DISA Valve","description":"The Rein Intake Manifold Adjusting Unit, also known as a DISA valve, is an OEM-quality replacement designed to restore lost torque and performance in specific BMW M54 and M56 engines. This component is crucial for variable intake runner systems, controlling a flap that redirects intake air to optimize performance across different RPM ranges. At lower RPMs, the flap closes to enhance low and mid-range torque, while at higher RPMs, it opens fully to allow maximum air volume for peak power.\n\nA malfunctioning DISA valve can manifest in several ways, including a noticeable sluggishness or unresponsiveness in the low to mid-RPM range. While the DISA valve itself may not trigger a specific fault code, its failure can lead to related diagnostic trouble codes such as fuel trim errors, engine misfires, lean conditions, and incorrect fuel mixtures. Additionally, a worn-out valve may produce an audible clicking sound from the driver's side of the engine bay as its solenoid attempts to actuate the flap, and a failing o-ring seal can introduce vacuum leaks.\n\nThis Rein DISA valve is manufactured to meet BMW's original design, fitment, and performance specifications, offering a cost-effective alternative to Genuine BMW parts. It comes with a two-year warranty. The valve is specifically designed for the M54 engine in various BMW models, including the E46 330i, 330xi, E39 530i, 2004-2005 E60 530i, Z3 3.0i, and 2003-2005 Z4 3.0i. It also fits the E46 325i\/325Ci models, but only those equipped with the M56 SULEV engine specification.","brand":"Rein \/","offers":[{"title":"Default Title","offer_id":52865942126904,"sku":"11617544805.Rein","price":244.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687604512.jpg?v=1787905748","url":"https:\/\/store.motormia.co\/products\/disa-valve-2","provider":"MOTORMIA","version":"1.0","type":"link"}
