CTS Turbo heat exchanger for BMW M2/M3/M4 G8X S58

CTS Turbo presents an upgraded charge-air cooler for BMW G8X M2/M3/M4 vehicles with the S58 engine, manufactured from 2021 onwards. Cooler and denser charge air contributes to more reliable ignition, reduced ignition timing pull and consequently increased performance.

The high-performance heat exchanger improves charge-air cooling efficiency and keeps intake air temperatures (IAT) as low as possible. It is designed for demanding high-performance driving and helps maintain optimal engine temperatures even in extreme conditions. This part is also known as a low-temperature charge-air coolant radiator.

Main features

• Direct fitment: specifically designed for BMW G8X M2, M3 and M4 models, so installation requires no modifications.
• Efficient cooling: the high-performance dual-pass core significantly reduces charge-air temperature and improves engine performance and reliability.
• Quality construction: manufactured from high-quality materials, with a robust aluminium core and advanced cooling fins.
• Optimal performance: suitable for road and racing use, providing consistent cooling to maintain maximum engine performance.
• Improved design: optimised cooling-fin spacing and a high-density core enable efficient heat dissipation.
• Low weight: despite its robust construction, the heat exchanger is lightweight, contributing to improved handling and lower fuel consumption.
• Plug-and-play installation: all the necessary mounting hardware for easy installation is included.

Benefits

• Longer engine life: lower intake air temperatures help prevent heat soak.
• More power and torque: lower intake air temperatures enable more efficient combustion, resulting in a noticeable increase in power and torque, especially at higher boost pressures on the S58 platform.
• Consistent performance: ensures optimal operation of the BMW G8X M2/M3/M4 on the track and in everyday traffic.
• Reliability: designed for demanding high-performance environments and extreme driving conditions.
• Protection: upper and lower stone guards protect the heat exchanger from road debris.

Specifications

• Construction: 100% TIG-welded aluminium, pressure-tested to 50 psi.
• Core: high-performance dual-row core measuring 633 mm × 458 mm × 40 mm.
• Compatibility: BMW G87 M2, G80 M3 and G82 M4 with the S58 engine.
• Finish: black finish for more efficient heat dissipation.
• Replaces original part numbers: 17-11-8-095-283, 17118095283.
• Weight: 8.17 kg.

The heat exchanger is suitable for vehicles with rear-wheel drive or all-wheel drive, a 6-speed manual gearbox and an 8-speed ZF8 automatic gearbox.

On vehicles with an automatic gearbox, the lower stone guard is not used. A smaller spacer is included for installing the transmission cooler on the left-hand side of the vehicle; secure the cooler using the factory bolt.

Suitable for: BMW M2 II (G87), BMW M3 VII (G20/G21/G80/G81), BMW M4 II (G82).
