The IAG Performance EJ Street Series Oil Pan features external cooling fins that help to disperse heat from the oil when air flows across them. It also has a bottom facing drain plug that is integrated into the lower cooling fins at the bottom of the pan, which allows for easy access to drain the pan and to make sure that all waste oil is eliminated during maintenance changes. The EJ Street Series Oil Pan is equipped with a 1/8th inch NPT port, making it compatible with several popular oil temperature sensors. In the case that the sensor port is not used, we’ve included a 1/8th inch NPT port to seal the sensor housing.
