The OE hot side silicone coupler at the intercooler of the Audi RS3 and TTRS is prone to failing at 30-32psi. It is also generally the first to fail out of the OE set.  This is to be expected when it is made with 2 ply reinforcement.   


Exceed far beyond these limits with the 5 ply reinforced and ringed coupler shown that is a direct fit replacement over the OE item.
