CSF Front-Mount Heat Exchanger (B48/B58)
£456.00 – £732.00
CSF’s Heat Exchangers for the chargecooling system on B48 and B58 engines provide a big increase in cooling performance, perfect for standard and tuned engines in need of a performance boost.
These chargecoolers fit the M140i and M240i as well as 1/2/3/420i and 1/2/3/425i models. When tuned, these engines experienced increased charge air temperatures which can not only be unsafe for the engine, but also rob power due to thermal inefficiencies.
CSF’s heat exchangers are a drop-in replacement for the original, requiring no additional modifications. They feature the largest 2-row, 68mm thick core available on the market with CSF’s B-Tube technology. They are also a triple-pass design for maximum cooling efficiency and have a removable rock guard just like the original.
CNC-machined fittings ensure a long-lasting and precise fit – available in polished silver or black. Replaces OEM part number 17118741830.
