STM Intercooler for 2017-2022 Audi RS3

Upgrade your 2017+ Audi RS3 intercooler with the STM Intercooler, crafted in-house from a 1000 HP-rated Garrett core featuring tig-welded aluminum end tanks and bead-rolled outlets. Pressure tested to 50 psi, this intercooler boasts a stock-replacement fit, seamlessly bolting up to your factory couplers.

Testing results on our stock 2018 RS3 revealed gains of +18 peak HP with similar torque gains from 4000-6800 RPM. This power increase shaved off nearly 1/10 of a second in the quarter-mile (tested on our AWD 500 Mustang Dyno), also boosting our speed by 2.8 MPH! Additionally, in a 40-130 roll, the new STM FMIC helped reduce time by 1.74 seconds. Expect even greater gains from modified and tuned vehicles.
