Superforma – RB AN20 Thermostat Housing
Superforma – RB AN20 Thermostat Housing
This water inlet thermostat housing is threaded to allow fitment of any AN20 female fitting. Suitable for use on all RB20/RB25/RB26 and RB30 engines. Perfect for aftermarket cooling setups.
Direct fitment to your engine block whilst retaining the use of your thermostat.
We would recommend an angled AN20 fitting to allow clearance from your inlet manifold.
