AIRTEC Motorsport Front Mount Chargecooler Radiator Upgrade for BMW B58. If you drive a BMW M140i, M240i, 340i or 440i and want consistent power on fast road or track, this B58 charge cooler radiator upgrade is the proven solution. Designed specifically for the B58 platform, this front mount chargecooler radiator delivers a huge cooling capacity increase to keep intake temps stable, reduce heat soak and maintain performance on stock, Stage 1 and Stage 2 tuned cars.
We have fitted and used this AIRTEC chargecooler radiator ourselves and our customers have been delighted with the results. Colder coolant, lower IATs, stronger sustained pulls and reliable temperature control in real-world driving and on repeated hard runs. It is a proper, bolt-on, plug-and-play heat exchanger upgrade that transforms B58 chargecooling.
Why upgrade your BMW B58 chargecooler radiator
Chargecooled engines rely on stable coolant temperatures. The factory radiator can struggle to control heat on tuned B58 cars, causing heat soak and power fade. AIRTEC’s solution uses a 90 mm thick, triple-pass core and a large-volume design to dramatically boost the system’s capacity and cooling efficiency.
- Triple-pass core forces coolant through the radiator three times for maximum heat rejection
- Capacity increases from 7.7 litres to 23.3 litres for a 203 percent gain
- Massive 90 mm core thickness for sustained cooling under load
- Direct replacement using OEM mounts and original coolant connectors
- Protective stone guard included to shield the core
- Durable powder coated black finish
- No cutting or trimming required
