I just did this tonight. Very easy. Removed VC, upper rad hose and then water neck to get proper torque on rear mounting bolt. Nice piece. Good vid Paul, Stock route uicp sucks I don’t miss it at all.
It’s the secondary air system. It’s for homologation. Used for anti lag system. Not sure what it does on stock cars with anti lag switched off. Mine has it but with stock ecu it’s either on or off done through mapping can’t be done on a switch with stock ecu. It’s just a valve with lines to the manifold. Pretty pointless on a road car but it’s quite cool.
