HF-Series intercooler for Ford Focus RS Mk.2 (305 PS)

This upgraded intercooler for the Ford Focus II RS is a highlight of the HF-Series range. The high-quality HFT cores provide excellent cooling performance, delivering strong performance even under demanding conditions while remaining highly robust. They offer high resistance to heat and do not warm up as much as comparable cores from other manufacturers.

The entire system is also designed for optimum flow. This means pressure loss is minimal, while the complete charge-air route has been developed using CAD flow analyses. This also includes the intercooler end tanks, which are made from high-strength cast aluminium.

Product benefits:

• significantly cooler charge air, improving combustion in the engine,
• quicker throttle response,
• improved flow.

This product is therefore suitable for both standard power and motorsport applications, as it also allows considerably higher power outputs. Each intercooler was built on the relevant vehicle, calculated using flow simulations and tested on the manufacturer’s own rolling-road dynamometer.

What does an upgraded intercooler actually provide?

To express the exact power increase provided by an intercooler, many unknown factors must be taken into account, such as factory power variation, other hardware modifications and the software used during measurement. This differs from vehicle to vehicle. As a rule of thumb for tuned engines, an increase of up to 5–10 % can be expected.

At least equally important is the fact that, at high outside temperatures, the intercooler helps prevent power loss or even activation of the temperature protection stored in many engine control units. This allows you to rely on the engine delivering its full power, whether it has already been software-tuned or remains standard.

Recommendation

We recommend using our HF-Series intercoolers together with hardware and software optimisation. Reducing back pressure, thereby relieving the turbocharger, and cooling the charge air, which increases the oxygen content in the combustion chamber and reduces thermal load, provides effective performance tuning. This makes efficient use of the potential of any turbocharged engine.

When carrying out hardware or software tuning, charge-pressure loss must not be overlooked. If vehicle power is increased through chip tuning, charge pressure is also increased in 99% of cases. With the standard intercooler, charge-pressure loss rises exponentially. The turbocharger must then work harder, increasing its thermal load and reducing its service life; higher rotational speeds also accelerate wear.

Our HF-Series intercoolers provide the perfect balance between cooling performance and charge-pressure loss. The development and distribution partner for this product is PS-Motorsport.

Suitable for: Ford Focus II (DA).
