I have bought a new blox im and 68mm tb. As u kno if u have a 00 si b16a2 the 5/16 coolant hose runs from block to tb from tb to im etc.. Well the blox intake manifold has the coolaant hose by runner 1 as the stock but the blox has a coolant hose coming off that as well and blox said to use that instead of stock setup but what about the extra tap/fitting from the block that ran to tb and im with the stock,manifold
