Proflow Water Neck, Billet Aluminium Swivel, Silver Anodised, 45 Degree, For Holden V8 253.308

Proflow's billet 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, 45, or 90 degree angle and come complete with stainless hardware.
