I am looking for the air hose from the air intake tube to the ISC valve. The one on the car has turned rock hard and had to cut it off to remove air tube so as not to break nipple off of air tube.
Lexus says it is no longer available. I have been searching the net but, have not found one yet. Anyone have a part number?
It is an odd size - a bit over 17 mm id. so, bulk hose won't cut it. It is also a formed hose so, making bulk hose work is an issue as well.
Open to suggestions.
