Review on 🔵 Mishimoto MMHOSE-SUB-ANCBL Ancillary Hose Kit - Subaru Impreza WRX/STI 2001-2005 Blue by Steven Saric

I ordered these hoses for my 2004 WRX. The package arrived without papers. The MFG website doesn't have a help chart either. They link to a video but it goes straight to installation and doesn't identify all hoses very well. There is a little house with the inscription "A non-return valve must be installed for this hose...". it can't be located in my engine bay maybe for STI?. This is easy to solve with a diagram! A 90 degree intake that goes under the coolant bottle is not suitable. You may need to trim it, or you'll end up with a sharp 80-85 degree bend. For such a price it was also necessary to supply clamps.
