This HF-Series Intake Upgrade Kit for the A4 & A5 B9 series with 1.4/2.0/2.9 and 3.0 TFSI engines is the perfect combination of an optimisation of the intake system in OEM look together with maximum performance.
The facts at a glance:
- Increase in volume thanks to upgrade top cover
- Air filter with 90mm funnel connection
- OEM optics
- 100% in-house development with 3D scan and flow simulation
- with oiled Pipercross air filter (reusable)
- Flow optimised air path
- Incl. upgrade intake hose and turbo inlet (depending on engine selection)
- maximum performance and efficiency
Note for the RS models: Unlike other manufacturers' inlet kits, ours does NOT require the engine cover to be cut. The kit fits without any further adjustment work
The development was carried out completely in-house.
With elaborate 3D scans, flow simulation and tests on the test bench, the race track and on the road, we have managed to create the optimum in power and performance in combination with a pleasant improvement in intake noise.
Suitable for both production vehicles and vehicles with performance-enhanced engines.
With the 2.9 TFSI engine from the RS4/RS5, we were able to measure an additional performance of +25HP and +40NM only by modifying the Intake on the standard engine (without software or other hardware changes).
We have achieved this result time and time again on 3 different vehicles. This shows the enormous potential that lies in our upgrade.
HF-Series
HF-Series is the first point of contact when it comes to fresh air supply in vehicles. With this brand, HG-Motorsport has combined professional research and production of high quality intake systems, intercoolers and air guidance systems. In addition to 3D scanning of the vehicle periphery for perfect fitting accuracy, this also includes long series of tests to combine the optimum components for each individual model. The result is racing products.
