"Don't gas engines require a turbo with an intercooler?"

Please explain the meaning of this sentence. I really do not understand... There are many, many gas.turbo systems running without an intercooler (low-boost systems.)

The way it is written ("a turbo with an intercooler,") it sounds like you think an intercooler is part of the turbo. I am confused by this...

Please elaborate. Intercoolers are separate from the turbo, itself.
