Honda Acura Block Plug Adapter Breather Fitting 10AN Catchcan B Series B18 B16
Honda B-Series to 10AN Block Plug Adapter 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 for 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.
This Fitting is made of Raw 6061 billet aluminum and is double O-Ring to prevent any leaks. Th bracket is made of titanium for light weight and strength.
Does not include any bolts, Motor should have a bolt in location from the factory.
***Note: B20 blocks don't have this port.
