ZERO/SPORTS COOL RADIATOR PANEL Ref: ZS-C/RAD-EC Genuine ZERO/SPORTS Cool Radiator panel is used to block air entering from the front opening from escaping between the gap opening before the radiator. In the original Subaru setup, some of the air escapes from the opening without passing through the radiator and hence losing cooling efficiency. It is proven that by adding this shroud, the water temperature can be lowered by 3-5C. |
