Manifold Heater for Cold Climates

the manifold will cool down fast enough as soon as you crack the throttle,
the aim of this is to help vapourise the accelerator pump shot in all circumstances and that it will do...

general running i.e any air flow will reduce, in seconds, the temperature of the base of the manifold on a hot or cold day

it just gets warm when the throttle is closed i.e at all times just before you need to make best use of an accelerator pump shot.

remember the original manifold was clamped to the exhaust manifold which will have conducted heat from one to the other regardless of whether the exhaust gas flap was open or closed. and of course exhaust is way hotter than coolant.
