Fittings

Shop Subaru AOS fittings at IAG Performance for WRX, STI, Legacy GT, and Forester XT models, including IAG Performance stainless steel AN breather fittings and quick-connect hose barbs. These fittings are essential for a clean, leak-free air oil separator installation, and the quick-connect design makes routine AOS maintenance and hose swaps far easier than working with traditional barbed fittings.
