{"product_id":"dual-core-engine-oil-cooler-for-bmw-n55","title":"Dual-Core Engine Oil Cooler for BMW N55","description":"The CSF Race-Spec Engine Oil Cooler (part #8145) is engineered to address the engine oil temperature issues commonly experienced by BMW N55 engines under sustained high loads or in high ambient temperatures. Owners often see oil temperatures exceeding 130°C and even reaching 140°C+, which can compromise engine component longevity and lead to potential failures.\n\nThis innovative cooler boasts a dual-core, in-series system, featuring an additional 5 rows of cooling on the rear side, offering approximately a 40% increase in heat rejection. It's converted to a single-pass design with a high-pressure return line for optimal flow. The construction utilizes CSF’s AC condenser technology with a 1-row, super high-pressure 26mm multi-channel microtube and a high-density, multi-louvred fin design to maximize surface area contact. This results in a temperature reduction of approximately 9°F-18°F (5°C-10°C) in engine oil temperature, depending on ambient conditions and load.\n\nDesigned as a direct replacement for the factory unit, the CSF Race-Spec Oil Cooler provides a \"drop-in fit\" with zero modifications required for installation. It accepts all attaching OEM components, including oil line connections, mounting brackets, and shroud\/ducting. The installation process does require an additional 1\/2 quart of oil for proper fill-up, bringing the total capacity to approximately 7.5 quarts from the OEM's 7 quarts.\n\nThis oil cooler is specifically designed for F-Chassis BMW models with the N55 engine. It is not compatible with F-Chassis SUV models, nor will it fit the F06 640i. Earlier E-Chassis models (e.g., E93 335i N55) require a different part number (CSF #8042).","brand":"CSF Dual-Core","offers":[{"title":"Default Title","offer_id":52687505948984,"sku":"8145","price":399.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687894491.webp?v=1784884866","url":"https:\/\/store.motormia.co\/products\/dual-core-engine-oil-cooler-for-bmw-n55","provider":"MOTORMIA","version":"1.0","type":"link"}
