Using carbon fibre brings obvious benefits of strength, lightweight and aesthetics. However, a part that is often forgotten is its low thermal conductivity, which means it reduces heat soak and transmission of said heat to nearby items. Keeping Inlet Air Temps (IAT’s) low is often a difficult part of developing induction systems, so replacing metal or plastic inlet solutions for FMINDK50 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.

The sound resonator and accordion ribs on the OEM inlet hose cause significant turbulence to the airflow causing a detriment to the engine’s potential performance. Our improved solution, FMINLH25 (included in this kit), gives you a host of performance upgrades, including:

• Improved induction noise.
• Multi ply silicone construction improves longevity of FMINLH25 over that of the OEM hose.
• 5 ply silicone construction will be able to handle strain of engine mapping far better than OEM hose.
• Increase of diameter at airbox end from 85mm to 90mm.
• Lifetime warranty.
