Description

Optimize your Subaru’s cooling system with the IAG Performance Wiggins Style Thermostat Housing, designed for 2002-2014 WRX, 2004-2021 Subaru WRX STI, 2013-2024 BRZ, 2004-2013 Forester XT, and 2005-2009 Legacy GT models. This premium replacement eliminates the restrictive OEM thermostat housing, enhancing coolant flow and cooling efficiency—critical for race and track builds where every degree counts.

Featuring a lightweight yet durable design, the housing uses a specialized Wiggins clamp for a flexible, tool-free connection that saves time during installation and maintenance. Unlike the stock unit that relies on rubber hoses and worm-drive clamps, this housing improves reliability and performance under high-stress conditions. Note that custom fabrication is required for the lower radiator hose assembly, and the -24 Wiggins clamp is sold separately.

Ideal for Subaru enthusiasts building race, rally, or track cars, this thermostat housing offers proven technology trusted across motorsport and industrial applications. Upgrade your cooling system today and experience better flow and easier serviceability with Subimods.
