Forge Motorsport have a worldwide reputation of making industry leading parts for an array of performance vehicles; as such we’ve been able to work with some of most knowledgeable professionals in the tuning industry to produce the most versatile Audi RS3 performance intake on the market. A special thanks to Litchfield Motors, MRC Tuning and KSF Motorsport who have helped our RS3 8V/8Y intake development achieve the final product you see today.  

3D scans of left-hand drive (LHD) and right-hand drive (RHD) RS3 8Y’s and RS3 8V’s gave us 4 separate vehicle scans that we could then pull together into one file that has allowed us to create one intake that fits all 4 variations. So, no matter where you’re based in the world or whether you have an 8V or 8Y RS3, the Forge Motorsport FMINDK47 is the intake for you.  



Trying to ensure that our performance intake is a one fit all solution also involved an understanding of how turbo inlets vary across the globe for the RS3 market. The OEM turbo elbow is an aluminium cast part with a 3” inlet tract that tapers down to the factory turbo charger cold side feed. Forge Motorsport offer and manufacture an upgraded silicone inlet elbow and turbo inlet adaptor (FMINLH9) not only to increase the area to the inlet tract but also the volumetric capacity. This has been increased to 3.5”and is the largest available product that fits RHD vehicles (due to space constraints with the brake master cylinder and is not physically possible to increase this size any further). However, this is not a problem on LHD vehicles, and as such there are various 4” variants available. To ensure our intake will work in conjunction with either the stock or any aftermarket inlet elbows on RHD or LHD vehicles we’ve incorporated an innovative solution that will be interchangeable if you wish to further enhance the engine performance of your Audi. 

FMINDK47 incorporates and includes modular couplers so that it can fit any size turbo inlet you may choose to run. The machined end of the carbon intake where it meets the inlet tract to the elbow has a 4”(102mm) threaded billet attachment which tapers up to the huge 6” pleated filter on the intake side. At this billet alloy junction, it enables the end user to have interchangeable adaptors. Having this amount of adjustment with a vast increase in airflow allows this product to be suitable for stock or aftermarket turbo inlet solutions whether manufactured from silicone or aluminium. This enables the enthusiast to interchange the adaptors depending on if its currently stock or modified. FMINDK47 will support your RS3 to literally any state of tune.  

Keeping inlet air temperatures (IAT’s) low is often a difficult part of developing induction systems, and several different variations were tested with FMINDK47. We decided on keeping the OEM air inlet to feed a specifically designed heat shield which sits flush up to the bonnet. An opening on the side opposite to the engine also helps with vehicles running stage 3+, as there is indirect airflow to this area and during testing a fully closed airbox caused restrictions.  

Using carbon fibre brings obvious benefits of strength, weight, and aesthetics. However, a part that is often forgotten is its low thermal conductivity, which means it reduces heat soak and transmission of heat to nearby items. Replacing metal or plastic inlet solutions for FMINDK47 will help decrease IAT’s and increase the volume of air supplied to your vehicles engine that is compressed by the turbo charger. This has a better effect on performance when cool as this is to provide the engine with more oxygen (denser air), thus improving the combustion in each cylinder. In addition, by regulating and reducing the air temperature, it also increases the reliability of an engine by keeping the AFRs (air fuel ratios) in each cylinder at a safe level, which in turn, can increase an engines power due to the air being cooler. A bigger bang is then created within the cylinder, providing the correct amount of fuel is added. This can equate to an increase in BHP and torque. 

We use SolidWorks CAD, 3D prints, and numerous dyno sessions to truly unlock the power. Simulation testing played a large part in the design process to help maximise the airflow. The 3D printed prototypes helped with comparing our simulation testing to real world driving conditions. This is a valuable comparison that is used in the top tiers of motorsport, now being brought to your vehicle.

Being able to test 3 different 8Y RS3’s on 3 different independent dynos has been of vital importance to our development process. One of these RS3’s was (at the time of writing) the fastest 8Y RS3 in the world making 682Whp with FMINT33, FMINLH9, FMINDK47 installed along with a TTE777 Hybrid Turbo charger, this proves the FMINDK47 has great CFM airflow ratings over the standard intake system on vehicles with such a high state of tune.

The other vehicles tested were a UK RHD 8Y running FMINT33. We then changed out from the OEM turbo inlet to FMINLH9 to confirm the differences in BHP with these extra modifications. We were also able to test on a LHD 8Y that was completely stock.  

With a completely stock tune vehicle we were able to see peak gains of 6BHP. However further analysis of the dyno graph shows that this peak BHP figure was produced 200RPM earlier (6097RPM instead of 6298RPM). Additionally, the power curves were smoothed across the entirety of the rev range, with gains seen across the board. To pull out some snapshots from the rev range as examples, at 3000RPM using just FMINDK47 saw an increase of 25BHP, and at 4500RPM there was an increase of 17BHP. Torque figures saw similar gains across the rev range, with a peak torque figure increasing by 17NM at around 100RPM earlier. When we analyse the dyno graph across the rev range, at 3000RPM using just FMINDK47 saw an increase in 55NM and at 4500RPM there was an increase of 23NM.  

The gains lower in the rev range are truly impressive from a driver perspective this is where the benefits can be felt and is what typically puts you in your seat when the throttle is pressed.

Vehicles with a stock tune, FMINLH9 and FMINT33 already installed hit a torque limiter earlier in the rev range with the addition of FMINDK47, which in turn can limit peak power results due to the engines ECU limiting power transmitted to the gearbox. So, if you have these three products installed, we highly recommend looking to tune your vehicle to really maximise the performance of the modifications installed.

It’s worth remembering that this is with a stock ECU and no tune. We know from the independent testing we also completed on mapped cars (such as KSF’s) that the Forge Motorsport products create unparalleled performance. 

It’s worth noting that this induction kit offers a massive amount of air to the EA855 EVO DAZA or DNWA engine, which is a must for anyone looking to push the performance of their RS3 when tuning to stage 1, stage 2, and beyond. Not only do you get the BHP performance benefits, but FMINDK47 also offers a greater induction noise from the engine; particularly when on boost, our product testers have reported a more responsive throttle which is to be expected from the impressive low down power gains the Forge intake provides.  

FMINDK47 is part of our acclaimed Hi Flow range and will ensure that your vehicle is getting critical cold air. Manufacturing this product our of carbon fibre has ensured that we can give you the biggest RS3 induction kit on the market, with the largest possible volume for maximum smooth airflow. Not only is the Forge part a better option for performance, but the carbon fibre really helps to give the engine bay some character. The weave of the carbon has been optimised to match the carbon on the intake manifold, which really shows the level of detail we put into our designs. The high-quality carbon fibre is prepreg 2x2 twill formed in an autoclave from billet tooling and finished with an anti UV gloss gel coat. The Forge Motorsport lifetime warranty on all hardware products shows the trust we have in the quality of our products while they are being enjoyed on your pride and joy. 

The kit comes complete with everything you need for installation, which can be carried out in around 1 hour, including a set of full colour instructions. For such an easy to fit product it truly does create some remarkable gains. 

*Please note - the filter is excluded from the Forge lifetime warranty*
