Most of u are aware that on many occassions people have found that the OEM TI pipe has worked loose and needed to be retightened.
Today i was replacing the oem rubber TMIC 90 deg outlet bend and found this pipe to be loose also. The clamp to the manifold was about 3to 4 turns loose.
It is a real pain to get at as the clamp bolt is at the rear and u need small hands to get at it. I replaced with silicone hose and replaced clamp with better quality and mounted tightening bolt in a more accessable position.
Any one loosing boost pressure or loss should inspect this pipe.
OTOMOTO in NSW have quality 4ply silicone material at reasonable prices and there fittings are extra long so as to assist in cutting to suit.
