I need to replace the green profile gasket. This is item # 2 on the lower diagram on page 130-35 of the Bentley manual. I understand that in order to do so I need to remove the supercharger intake air duct, item # 3 on that same diagram. In order to remove that, is it necessary for me to remove the intercooler output air duct, item # 5 on the lower diagram on Bentley page 130-34? TIA.

 

You will need to remove the intercooler, BPV intake horn, throttle body, brake booster vacuum source, MAP lead, and the black intake duct to replace the gasket.

Not a hard job, all in all we have them replaced in about an hour with a hoist and given skill set. Just make sure that the surfaces are clean and that the intercooler boots don't get tucked or improperly seated and you'll be fine.

 

already came to that conclusion and it has now been removed.
