Hi all,

Noticed today that the right (passenger side) top intercooler hose is really soft and squishy compared to the left one. Can't see any splits. Would this cause issues ? I take it they have to be firm/solid.

Not necessarily, sometimes they can seem soft because they are old. Look for splits, or listen for air noise when running.

New ones feel soft, old ones feel hard.
I replaced both of mine and was surprised at the difference
