STM Intercooler for 2017-2022 Audi RS3
The STM Intercooler for the 2017+ Audi RS3 is made in-house from a 1000 HP-rated Garrett core with tig-welded, aluminum end tanks and bead-rolled outlets. Pressure tested to 50 psi. This intercooler features a stock-replacement fit and will bolt right up to your factory couplers!
Testing results on our stock 2018 RS3, we saw gains of +18 peak HP with similar TQ gains from 4000-6800 RPM. This increase in power helped us knock off just about 1/10 of a second through the quarter mile (testing done on our AWD 500 Mustang Dyno). It also gained us 2.8 MPH!! The last test we decided to do was a 40-130 roll. With the new STM FMIC installed, we were able to knock 1.74 seconds off!!! We would expect much larger gains from modified and tuned cars.
Vehicle Fitment:

• 2022 models do not need the spacer.
