Description
This is a metric to AN adapter made of steel with crush washer and o-ring on the metric side. This fitting screws directly into your GT series turbo and directly into the water fitting in the back of your late model factory engine block where the turbo charger cooling line goes. Using these fittings are the right way to run coolant lines; no more leaky banjos or ill fitting parts, do it right the first time, these are the way to go.
