The Aeroflow Performance billet thermostat housings are a three-piece design that allows for correct positioning of the outlet to suit a large array for applications especially in conversions where small can be an issue. Machined from T6-6061 billet aluminium and allows for a full 360-degree swivel rotation for ease of installation. All Aeroflow Performance thermostat housings feature an O-ring base flange, as opposed to using the factory paper style gasket, this ensured a superior leak free seal. Each thermostat housing outlet can be untreated exposing a female 1-1/4”-20 thread to adapt a AN fitting or a larger barb fitting for custom applications. Available in several anodised finishes.
