A larger front-mounted heat exchanger for the water-cooled charge air cooling system on BMW F-Series cars with B48, B46 or B58 engines. Heat soak in this system makes the ECU pull power on track days and hard road driving; the larger radiator adds cooling capacity to keep intake temperatures down.
Features
- 66% larger core volume than the original radiator.
- Dual-row core, 48 mm thick, with 120% more cooling surface.
- Triple-pass layout, so the water passes through the radiator three times and the core surface is fully used.
- Full aluminium construction with TIG-welded end tanks.
- Larger fluid capacity.
- No modifications needed to fit; mounting points for the original transmission cooler are included.
