Increased Oil Capacity: This cover has an increased oil capacity over stock for better performance over a longer duration. Built-in Internal/External Fins: Built-in internal and external fins transfer heat from the oil to the outside air for maximum cooling. Magnetic Plugs: This system incorporates a magnetic drain and deep reach fill plug to capture loose particles for maximum protection. Calibration Plug: Calibration plug set to the factory oil level to eliminate overfilling. Oil Level Sight Glass: A pre-installed oil level sight glass allows quick and easy oil inspection.
