 FAQ and answers:

  • Possible issues this part corrects:
  • When the throttle bodies on a turbocharged engine closes, the high-pressure air in the intake system is trapped causing a pressure wave to be forced back into the compressor wheel. The resulting collision of pressure waves creates an effect similar to cavitation producing the unique (turbo bark) noise.
