Product Information

The AWE 4.5 S-FLO Open Carbon Intake System is a high-performance intake system designed for the Audi RS3 and TTRS. It includes a 2.5T carbon filter tube, a 4.5in cone filter, a filter mounting plate, a flex coupler, a 2.5T turbo inlet tube, a turbo coupler, worm drive clamps, carbon tube bolts, oversized flat washers, and a cable tie. The AWE DV Adapter Kit for 2019+ Models is also available as an additional component for the newer models.

It is important to refer to the manufacturer’s service manual for precise torque specifications on all OEM fasteners. The engine may be very hot, so it is recommended to allow adequate time for the system to cool down before disassembly.

Product Usage Instructions

Refer to the manufacturer’s service manual for precise torque specifications on all OEM fasteners.
Begin by removing the engine cover by carefully pulling it upward.
Remove the OEM inlet duct by removing the 2 screws pointed out in Figure 2-1, then carefully push it towards the engine and remove it from the vehicle. Save part and hardware for reinstalling later.
Loosen the 2 hose clamps holding the OEM intake hose in place, then carefully remove the intake hose from the intake.
For pre-2018 models only, remove the hose from the OEM intake by squeezing the clamp tabs together and wiggling the hose off.
For 2019+ models only, remove the 2 bolts on the engine side of the OEM diverter valve hose. This will allow the diverter valve hose to be removed with the OEM intake. Note: These 2 bolts will be reused in the install of your AWE diverter valve.
