When testing on the second day, the ambient temperature was one to two degrees hotter, allowing us to have near identical test conditions. The oil gauge on the dashboard never exceeded 120 degrees, allowing us to complete more laps without the worry of oil degrading. \u003c\/p\u003e\n\u003cp\u003eWhen looking at the data gathered from the oil temperature sensors we had installed in the inlet and outlet of the oil cooler, we saw temperatures as high as 125 degrees at the inlet and as high as 110 degrees at the outlet, so only 15 degrees being taken out by the oil cooler. When compared to the data when fitted with our AIRTEC Motorsport oil cooler, the maximum temperature into the oil cooler was 123 and the maximum outlet temperature was 76 degrees, so 46 degrees of temperature pulled out of the oil, which is an impressive\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e205%\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003emore than the standard oil cooler was able to do. \u003c\/p\u003e\n\u003cp\u003eOn average, the temperature decrease by the\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eAIRTEC Motorsport\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eoil cooler was\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003edouble\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003ethat of the original oil cooler. \u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.youtube.com\/watch?v=pxJ-3A6Gu5k\u0026amp;t=151s\"\u003e\u003cstrong\u003eFULL VIDEO OF THE TESTING AVAILABLE ON OUR YOUTUBE CHANNEL HERE\u003c\/strong\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg decoding=\"async\" src=\"http:\/\/www.airtecmotorsport.com\/wp-content\/uploads\/sites\/4\/2025\/08\/2.jpg\" width=\"567\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003ePlease note: \u003c\/strong\u003e2007 or early 2008 models will require the original oil line connectors to be modified OR replaced.
