Where is the cooling pipe of bj40?

Beijing BJ40 comes with a detachable rear ceiling and roof, revealing two hard-core steel pipes, which are obviously toys. The intercooler pipe is installed behind the ghost mask, not at the bottom of the gas dam, so the model has enough space to take the original pipe.

The intercooler tube is two tubes, one from the rear end of the turbine pump body (turbine? A compressed air outlet, not a waste gas outlet) is connected to the intercooler, another pipe is connected from the intercooler to the throttle valve, and the rear end of the throttle valve is the intake manifold.
