Twin Air Oil Cooling System YZ450F 23-..

By dramatically lowering the temperature of the oil and your water temp accordingly,TwinAir"s patented oil cooler can keep your rides and your engine at peak performance longer. 

TwinAir's solution is a revolutionary improvement. Zigzag fins were, at best, a passive tactic. Longer cooling tubes got in the way and were less effective. Unlike traditional coolant-based approaches that tap into the water cooling system, TwinAir's design is the first air-cooled driven solution. From a mounting panel behind the radiator, flexible hoses circulate oil to a unique, tubular cooling grill of 3 sets of 3 short pipes designed to maximize heat exchange. 

The TwinAir Oil Cooler kit includes everything you need: heat exchanger, mounting hardware, oil filter cap, hoses, clamps and step-by-step instructions

• Twin Air's Oil Cooler's unique tubular heat exchanger cools the oil by running the oil through the tubes via a 3 chamber element.
• The 6mm ID rubber hose was our choice to maximize heat exchange and maintain optimal oil pressure. Our testing of a rubber hose versus a stainless steel braided hose, the rubber hose had better heat exchange and maintained engine oil pressure.
• The Twin Air Oil Cooler is mounted behind the left side radiator and comes with all the necessary hardware for mounting.
