The high performance tube spec, along with the high-efficiency multi-louvered fin design allows for maximum surface area contact and an approximate 40% increase in heat rejection. The High-Performance Race-Spec Oil Cooler directly replaces the factory unit, easily bringing engine oil temperatures down to a consistent and manageable level, even under extreme \u0026amp; extensive driving conditions.","brand":"CSF","offers":[{"title":"Default Title","offer_id":47549746938010,"sku":"CSF8145","price":399.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0430\/4237\/3786\/files\/30db3487174ed42ccc0fab0ad577bc7dL.jpg?v=1772865135","url":"https:\/\/envisiontuning.com\/products\/csf-11-16-bmw-135ix-5-door-f20-m135ix-3-door-f21-race-spec-oil-cooler","provider":"Envision Tuning","version":"1.0","type":"link"}
