As a result, there is risk of damaging the transmission, so the car’s ECU will automatically limit the engine’s torque output and put the car into a limp mode. It can even cause permanent damage, if it persistently overheats.\u003c\/p\u003e\n\u003cp style=\"margin-left:0px\"\u003e\u003cstrong\u003eThe Solution\u003c\/strong\u003e\u003cbr\u003eMaking full use of all the available space behind the bumper, the AIRTEC Motorsport transmission cooler utilises a core design that is a massive \u003cstrong\u003e218% bigger\u003c\/strong\u003e than standard and \u003cstrong\u003e91% taller \u003c\/strong\u003ethan original, which equates to a frontal area\u003cstrong\u003e increase of 118% \u003c\/strong\u003eto help cool the extra capacity. \u003c\/p\u003e\n\u003cp style=\"margin-left:0px\"\u003eProven to work on track, the AIRTEC Motorsport cooler was tested to offer a huge \u003cstrong\u003e100% increase\u003c\/strong\u003e in heat rejection, allowing the new cooler to provide improved cooling, preventing the overheating issue. \u003c\/p\u003e\n\u003cp style=\"margin-left:0px\"\u003eThe comprehensive kit also comes with a real carbon fibre air scoop that matches the profile of the new bigger core, as well as an aluminium vent to fit in the inner wheel arch to help extract warm air, creating an improved air flow to further aid cooling the new, larger core design. \u003c\/p\u003e\n\u003cp style=\"margin-left:0px\"\u003eFinished in a high-quality powder-coated black finish, the cooler is a direct replacement fit and comes complete with detailed fitting instructions. \u003c\/p\u003e\n\u003cp style=\"margin-left:0px\"\u003e\u003cstrong\u003eTESTED ON TRACK\u003c\/strong\u003e\u003cbr\u003eIn May 2025, we ventured over to the iconic Nürburgring in Germany to complete a two day, back-to-back test in order to collect data as part of the track testing programme for our newly developed E9x M3 cooling package; in particular the engine oil cooler DCT gearbox oil cooler.
