This Oil Cooler Kit is a high quality accessory designed to help the Honda horizontal engine keep cooler. Air-cooled engines run hotter when modified (i.e. big bore kits) and/or subjected to heavy loads such as racing use. This kit will help the engine’s durability and reliability by circulating the engine oil through a cooler reducing the engine’s oil temperature. The kit includes the following: - Lightweight aluminum 4 row oil cooler (not a 3 row as many others sell). - AN fittings - Crimped, braided lines - No hose clamps that could easily come off or leak nor cheap rubber hoses. - Intake type mounting bracket - CNC Billet Right side cylinder head cover adapter (red) -  This oil cooler mounts to the intake manifold for clean and nice looking fit.
