Description

Billet Specialties thermostat housings not only look good, but they also get rid of leaky paper gaskets thanks to their O-ring seal design. You can choose the conventional vertical housing or the high-tech 360 degree swivel housing. They're available straight-up or with a 0, 15, or 45 degree angle and come complete with stainless hardware.
