{"product_id":"3-bar-map-sensor-9","title":"3 Bar MAP Sensor","description":"The Kerma TDI three-bar MAP (manifold absolute pressure) sensor, Bosch part number 0281002976, is a crucial component for monitoring turbocharger pressure and intake air temperature. It offers an expanded operating range of 3 bar (approximately 22-23 psi of boost) compared to the factory 2.5 bar sensors found on many TDI models, which are typically limited to around 16-17 psi with stock ECU settings.\n\nThis sensor is highly recommended when upgrading the turbocharger in ALH, BEW, or BRM engines, as it allows for higher boost pressures necessary for improved performance. Touaregs and Passats often come equipped with this 3-bar sensor from the factory, providing an expanded operating range over their original 2.5 bar counterparts. Without this upgraded sensor, performance gains from a new turbo may be limited by the stock sensor's capacity.\n\nCrucially, installing this 3-bar MAP sensor requires notification to your tuner, as improper adjustment can lead to dangerously high boost pressures that could damage the turbo. For ALH-engined cars, fabrication of an adapter grommet or gasket is necessary for installation, although a billet aluminum adapter is also offered. This sensor is not compatible with A3\/B4 cars, which feature a MAP sensor integrated into the ECU.","brand":"Kerma TDI","offers":[{"title":"Default Title","offer_id":52686448591160,"sku":"0281002976","price":33.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/658753074.jpg?v=1784874007","url":"https:\/\/store.motormia.co\/products\/3-bar-map-sensor-9","provider":"MOTORMIA","version":"1.0","type":"link"}
