Built-in internal and external fins transfer heat from the oil to the outside air for maximum cooling. This cover incorporates a magnetic drain and deep reach fill plug to capture loose particles for maximum protection. A calibration plug is set to the factory oil level to prevent overfilling. Included oil level sight glass allows quick and easy oil inspection.
