Description
Upgrade the cooling system of your Mercedes-Benz CLA45 AMG with the Untd. Performance Radiator, designed to provide increased cooling capacity and improved thermal management for high-performance street, tuned, and track applications.
The high-output 2.0L turbocharged AMG engine generates substantial heat, particularly under increased boost, repeated acceleration, spirited driving, and demanding track conditions. The Untd. Performance Radiator is designed to improve heat dissipation and help maintain more consistent coolant temperatures, allowing your CLA45 AMG to perform reliably under demanding conditions.
Whether your vehicle remains near stock or has been upgraded with an ECU tune and supporting modifications, this radiator is a practical cooling upgrade for maintaining stable operating temperatures.
Key Features
- Upgraded Cooling Capacity – Designed to improve heat dissipation and cooling efficiency compared to the factory radiator.
- Improved Thermal Management – Helps maintain more consistent coolant temperatures during aggressive driving.
- Reduced Heat Soak – Increased cooling capability helps manage rising temperatures during repeated pulls and high-load operation.
- Performance-Oriented Design – Ideal for tuned, modified, and high-performance CLA45 AMG applications.
- Durable Construction – Built to withstand the demands of performance street and track driving.
- Direct-Fit Design – Designed specifically for the Mercedes-Benz CLA45 AMG platform.
- Installation Hardware Included – Includes required installation hardware where applicable.
- Tune-Friendly Upgrade – Compatible with both stock and tuned vehicles without requiring ECU calibration.
Estimated Performance Gain
A performance radiator is primarily a cooling and reliability upgrade, rather than a direct horsepower-producing modification. Its main advantage is helping the engine maintain stable operating temperatures, particularly during sustained high-load driving.
| Vehicle Setup | Estimated HP Gain | Estimated Torque Gain |
|---|---|---|
| Stock Vehicle | ~0–2 HP | ~0–3 WTQ |
| Stage 1 Tune | ~0–4 HP* | ~0–5 WTQ* |
| Stage 2 / Performance Setup | ~0–5 HP* | ~0–5 WTQ* |
*The radiator itself does not directly add significant horsepower or torque. Any measurable improvement is primarily related to improved thermal control and reduced heat-related power loss during demanding driving conditions.
Actual results will vary depending on ambient temperature, vehicle configuration, ECU calibration, supporting modifications, driving conditions, and overall cooling-system condition.
Why Upgrade?
The CLA45 AMG’s 2.0L turbocharged engine produces significant heat under high boost and sustained load. As power levels increase, maintaining proper coolant temperatures becomes increasingly important for consistent performance and long-term reliability.
The Untd. Performance Radiator provides increased cooling capability to help manage thermal load and maintain more stable operating temperatures. This makes it an excellent supporting modification for tuned CLA45 AMG vehicles, spirited street driving, repeated pulls, and track use.
Improved cooling can help minimize heat-related performance reduction and allow the engine to maintain more consistent operation during demanding conditions.
