These fittings will work for any b-series motor which has the black box on the back of the block. It just gives you another port to hook up a catch can. This fitting will come in real handy to those who only want to use one port on the back of the block. You don’t have to take off the stock 28mm plug on the back of the block, which can be tough if the motor is still in the car.

Note: B20 blocks don’t have this port.
