Upgrade your 2017+ Audi RS3 intercooler with the STM Intercooler that 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:
2017-2024 Audi RS3
• NON USDM models require the USDM crash bar in order to fit without cutting, otherwise cutting or removal of stock crash bars will be necessary.
• You can reuse your OEM clamps, but if you'd like to upgrade, we recommend these Vibrant 2.75" T-Bolt Clamps (2794)
• 2022 models do not need the spacer.

Why Drivers Choose FAST of West Chester

  • I can't recommend this place enough. Being able to trust a shop in the performance world is big. The 2hr drive to get there, is worth knowing the job will be done right. Very happy to have found this shop, to
    support my builds going forward.

    Donald Wojnar

  • I recently had the pleasure of working with FAST of West Chester for some performance upgrades on my 2022 WRX, and the experience was nothing short of exceptional. I opted for a Borla S-Type exhaust and Cygnus Coilovers, and the team at FAST nailed the installation, fitment, and setup to a T.

    Adam Cranston

  • The team at FAST are excellence in every way. First, I consulted with Dave on mods for my HPDE track car. He listened and advised me on the best parts & mods to achieve my goals. He was patient & gave me space to research the options presented & worked with me through several changes before we built. Second, the build execution was flawless, proper heat shielding, bracing and poly everywhere. All components worked as advertised.

    Bryce Budd

  • This place has been my go to shop for all things Subaru. From simple service to performance parts and tuning, they have been top notch.

    William Brunell

  • Excellent shop. They installed a Cobb Stage 2 DP and Whiteline Sway bars and end links on my 2013 WRX. The work was done right and clean. The estimate was accurate. They were very knowledgeable, friendly and gave me the straight scoop on exactly what I was getting for the money
    and what I needed to get where I want to be with it. I'd recommend them
    to any car enthusiast.
