The Aeroflow Performance press in adapter for the Ford Falcon BA-BF and FG Barra engine is a great way to easily install custom water lines. This billet adapter inserts into the same spot as the factory hard line pipe on the thermostat housing in all 6-cylinder Barra engines. This is great for those who want to remove/replace any of the OEM factory water lines with motorsport style hoses and Dash fittings. This fitting is provided with a female -8ORB as well as a new O-Ring for installation. Sold individually in hard anodized black finish.
