IAG SUBARU AN-STYLE THERMOSTAT HOUSING


THE IAG AN STYLE THERMOSTAT HOUSING

The IAG AN Style Thermostat Housing is the perfect upgrade for those transitioning from rubber OEM Subaru hoses to aftermarket AN hoses. This precision-engineered thermostat housing is designed to replace the factory unit in the following Subaru models- 2002-2024 WRX, 2004-2021 STI, 2004-2021 STI, 2004-2013 FXT, 2005-2009 LGT and 2013-2024 BRZ. It ensures a reliable and secure connection with aftermarket AN components, while providing optimal coolant flow for your Subaru’s cooling system.

ADVANCED ENGINEERING

The IAG AN Style Thermostat Housing is a significant upgrade over the OEM setup, which relies on rubber hoses and standard worm-drive clamps. While the stock system is adequate for street use, it lacks the reliability needed for high-performance applications. Our AN Style Thermostat Housing ensures a leak-free, robust seal that can withstand the demands of serious builds, thanks to its superior construction and protective finish.

HIGH-PERFORMANCE ALUMINUM DESIGN

IAG’s AN Style Thermostat Housing is precision machined from robust 6061-T6 billet aluminum. Unlike cast aluminum, billet aluminum offers superior strength, enabling it to endure higher levels of heat, stress, and strain. This thermostat housing has a flat 2 bolt OEM-style mounting flange on one side, along with a -20 AN male threaded end on the opposite side. Additionally, the housing features a sleek black anodized finish, providing enhanced protection against corrosion.
