The Jagg 10-row Low Mount oil cooler system is designed to deliver and keep a low-profile. The single-pass HyperFlow oil cooler is optimized for the Twin Cam engine and consequently works great on Evolution too. This cooler offers significantly more cooling surface-area than its closest competitor and ensures unsurpassed flow, heat rejection and the best heat-exchange, all while hiding neatly behind the fender and beneath the voltage regulator. All cooler kits come with Jagg's unique sandwich style satin black anodized thermostatically controlled offset oil filter adapter that installs between the stock oil filter mount and the filter. This provides an easy access point to the bike's oil supply for the installation of the oil cooler. All Jagg 10-row Oil Cooler Systems are supplied complete with the oil cooler, offset oil filter adapter, all necessary hardware and detailed, easy-to-follow installation instructions.
