HF-Series intercooler set VAG 2.0 T(F)SI EA888 Gen.4 (e.g. Golf 8 GTI, Leon KL, ) (HGICKVAG21-V3M)

This intercooler for the VW Golf 8 GTI is a highlight of the HF-Series range. The high-quality bar ’n’ plate core has excellent cooling properties to deliver top performance even in poor conditions while being very robust. It is highly resistant and does not heat up as much itself as comparable cores from other manufacturers. In our tests, at an outside air temperature of 17.5 degrees we achieved an intake air temperature of only 23 degrees. Even with our big stage 2 to 457 PS in e.g. the Golf 8 Clubsport/R, at full load we are at most 9.5 degrees above the outside air temperature. At the same time, the entire system is also designed for the best possible flow. This means that the pressure loss is minimal and the entire charge-air path has been developed for optimum flow using CAD flow analyses. This also includes the end tanks, which are made of high-strength cast aluminium and feature our WAY FIN TECHNOLOGY. This is an extra guide fin inside that guarantees even and optimal filling of the entire core. In addition, the intercooler’s inlet and outlet diameters have been enlarged to 70mm and, combined with the reinforced SF-Hoses silicone hoses included in the scope of delivery, provide the perfect preparation for a performance upgrade. This intercooler has a TTG (parts type approval) and has been tested in this certificate together with all other components available from us, provided they have a certificate. (Under “Fits” you will find an exact assignment of all vehicles.) Here you will find all other items tested in the certificate for your engine: EA888 Gen.4

To express the exact additional power of an intercooler in figures, many unknown factors have to be taken into account, such as: power variation from the factory, other hardware modifications and the software used for the measurement. This differs from vehicle to vehicle. As a rule of thumb, on tuned engines you can expect up to 5% - 10%. But what is at least as important: whether your engine is already optimised or is to remain standard in terms of software, you prevent a loss of power, especially at high outside temperatures, or even reaching the temperature protection stored in many ECUs, and can therefore always count on your engine’s full power. Recommendation: use our HF-Series intercoolers as a combination of hardware & software optimisation. Reducing the back pressure (relieving the turbocharger) and cooling the charge air (more oxygen in the combustion chamber + thermal relief) results in a performance tune that makes efficient use of the potential of any turbocharged engine. When you look into hardware or software tuning of your vehicle, you must not ignore the factor “boost pressure loss” either. If you increase your vehicle’s power with chip tuning, the boost pressure is also raised in 99% of cases. With the standard intercooler, the boost pressure loss rises exponentially. This means that the turbocharger has to work even harder, so the thermal load on the turbocharger rises and its service life falls, or it wears faster due to high speeds. With our HF-Series intercoolers we strike the perfect balance between cooling effect and boost pressure loss.
