Intercooler Upgrades for your Citroën C4 Cactus
An upgraded intercooler can help keep intake temperatures under control during repeated acceleration or track use. We help choose one that suits the engine's airflow, fits properly and allows the rest of the cooling system to work effectively.
What an intercooler upgrade can improve
The intercooler removes heat from air compressed by a turbo or supercharger. Better control of that temperature can help the engine maintain more consistent performance when worked hard.
- Cooling capacity matters most when temperatures rise over repeated acceleration or longer periods under load.
- The size and design need to balance cooling with how easily air can flow through the intercooler.
- The benefit depends on the current cooling system, power level and how the car is used.
Supporting upgrades
We will check the intercooler, pipework and mounting together, including any extra parts needed for a proper fit.
- The installation needs to preserve radiator airflow and clearance around the air conditioning and crash structures.
- Hoses, clamps and sensor connections need to suit the car and the new intercooler.
- Existing boost leaks need attention, and the fitted pipework needs checking before tuning.
Custom tuning and dyno testing
We can check the results on the dyno and adjust the tuning where the change affects airflow or boost control.
- Intake temperature readings over repeated runs show how well the intercooler controls heat build-up.
- We check that actual boost follows the requested level and review fuelling, with ignition checks where applicable.
- Testing also helps show how quickly intake temperatures recover after hard use.
