Aeroflow Bolt In Breather Bulkhead

Aeroflow bolt in valve cover breather adaptors are the perfect setup for your catch can/breather system on your engine without welding anything to your valve covers. Simply either use your current breather hole and drill it out to the correct size or start a new hole for this bulkhead fitting to screw on. This will allow the adapter to poke through your valve cover with a male AN fitting and is held in place with the included bulkhead nut, it allows for the use of braided style AN flare hose ends etc. to be used without having to weld your valve covers. Each adapter features large CNC machine drill ports similar to what you would find on a banjo style fitting are located on the bottom. This allows for maximum breathing compatibilities in various AN sizes from -10AN to -12AN, finished in either blue, black or silver anodized.
