I have 2007 Rwt Road Warrior 6.6 liter Durmax Diesel. I have a big problem that I can not solve. The CAC Cold Air / Intercooler pipe that goes to the turbo the Gmc # 25781940 has become obsolete. The Duct has a worn hole in it, by rubbing against the ac line. I check all eight GM dealers in
U.S.A they show the part however GM has sent a entirely unrelated different wrong part, so I have struck out. I check all outlets that carries Duramax diesel engine parts and a few junk yards and Road Warrior parts store, four vendors that make tubing like (Banks) no luck ! Any suggestions Have you Diesel owners had this problem with replace engine parts.
