No, you won't have to worry about any temperature increases or decreases. The foil is only there to keep the insulation around the pipe for noise dampening. Ford didn't want customers complaining about the turbo spooling sound (can you actually believe SOME
people didn't want to hear this!!!
), so they wrapped the intercooler pipe with insulation.
