The purpose of the engine oil cooler is to allow the engine's cooling system to remove excess heat from your oil. High performance vehicles produce higher heat levels than your average factory vehicles. Therefore, your OEM parts wont be able to withdraw at the rate needed for your modified engine. Mishimoto Oil Coolers ditched the lightweight design for a full aluminum, TIG-welded bar-and-plate cooler for added strength and cooling in your vehicle . The bars and plates are a much more robust form of heat exchanger core construction intended for improved heat transfer and have the strength to shrug off potential road debris, keeping your oil temps down, and where it should be!
