Your TT
Pick your year to see what fits.
There was no 2007 TT in the US. The 225, 3.2 and TTS are always quattro, and every TT from 2010 on is quattro.

Why do it
The stock side-mount intercoolers are small and heat up when you drive hard. A big front-mount keeps the intake air cooler, so power holds steady, and it matters most on a tuned car.
Heads up
Fitted only to the 225. Your kit's instructions come first, since the video uses a different brand.
Tools you'll need

For:
Safety first
- Park on flat ground, set the parking brake and chock the wheels.
- Never get under a car held up only by a jack. Use jack stands.
- Let the engine and exhaust cool first.
- Disconnect the battery before unplugging electrical parts.
- Wear safety glasses.
- If something doesn't match your car, stop and ask a shop.
Follow your part's instructions and your service manual's torque specs.
