I am refering to engine oil cooler. In fact, all such coolers (gearbox, cvt, engine oil) are basically the same. Only difference is the need for an adapter (to divert oil to cooler from the oil filter and then back again). The engine bay of the lancer is pretty hot after running around. Did not overheat though...but just like to cool it down a bit while driving. Hmmm...maybe an airscoop like the EvoX will get more air to the engine bay
(I am not too worried about the cvt oil getting hot as I had DIY a CAI to the OEM cooler. Had done some continuous running under hot weather without problem)
