The Mini engine has the unique feature of sharing its oil between the engine and the transmission. Thus keeping the oil temperature under control will greatly impact both life expectancy and performance of both engine and trans. One of the best options (as found on almost all original "S" models) is the use of a front mounted oil cooler. This cooler set-up can be fitted to any and all models prior to the 12A engine (circa 1992) with this handy DIY kit. Comes complete with 13 row oil cooler, a set of hoses and a pair of mounting brackets for locating the cooler right behind the grille.
