ADVANTAGES- Made of high quality T-6061 aluminum. It can be used to cool engine oil, transmission and rear differential. FUNCTION- Keep the oil temperature low to prevent damage or even seizure of the engine. HOW IT WORKS- The 10-row oiis basically like a radiator to cool your oil. Install the engine oil in a reasonable location with good air, your engine oil will enter the engine oil from here, and then reflux and cool down, and ensure that the engine oil is within a certain working temperature range. ADAPTATION- This is a universal oikit. The design of this oiis smaller and lighter, suitable for narrow spaces and meet the needs of more lines at the same time. WHY DO WE NEED AN OIKIT-When the engine rotates at high rpm under high load, it will generate friction, and the heat generated by friction will be transferred to the oil instead of overheating. After the engine oil is decomposed, it cannot be lubricated well, thus shortening the service life of the engine.
