Re: B16 Intake manifold question
I think that is a USDM ITR manifold, yes. The missing part is the fast idle thermo valve (FITV). Its a throttle plate bypass valve with a wax pellet that melts when the coolant reaches a certain temperature, which then closes the valve and bypasses less air past the throttle plate.
