The M8 engines come with oil coolers that circulate oil to the heads and the majority of the oil returns to the stock oil cooler.  The stock oil cooler simply is not enough to keep the M8s from overheating in traffic and city riding.  Unlike our UltraCool Oil Coolers for the Twin Cams that replaces a stock oil cooler, our Side Mount UltraCool Oil Coolers for the M8s work with the stock cooler to cool all of the oil.  This works incredibly well and with a FLO Oil Filter our 3.0 UltraCool Oil Coolers give the M8 engines the performance of a FULLY liquid cooled!  Don't believe that bold statement?  Just read the reviews by clicking on "Reviews" at the top of the page
