August 4, 200718 yr When cleaning the throttle body I noticed that this hose was all cracked up. It's soft foam, not a traditional hose, so I'm wondering what it is and if I need to worry about it? '98 Impreza L 2.2L As always, thanks for helping out a newbie!
August 4, 200718 yr Not to worry, thats a foam wrap to keep the heater hose from rubbing on the support that is right there at it.
August 5, 200718 yr You may want to wrap that foamy covering over the heater hose with some electrical tape to keep the cracked foamy part from breaking off in chunks.

Even some friction tape would be better than nothing... that's what I used on my Forester, and it looks like it was supposed to be there in the first place.
