Racingline Air Intake System Audi Mk2 TT 2.0 TFSI

Racingline Air Intake System – Audi Mk2 TT 2.0 TFSI (VWR121020)

The Racingline Cold Air Intake System is a direct upgrade for the Audi Mk2 TT fitted with the 2.0 TFSI K03 engine. It replaces the restrictive factory airbox with a free-flowing, hand-built design that helps your engine breathe more easily, supporting better power delivery, sharper throttle response and a more engaging induction sound.

As an authorised UK Racingline dealer, we supply this intake as a complete, ready-to-fit kit. It retains all original mounting points, so installation is straightforward without modifications to the car.

What This Intake Does for Your TT

The standard Audi intake is designed with noise reduction and mass production in mind, which restricts how much air the engine can draw in. Replacing it with the Racingline system reduces those restrictions, allowing the 2.0 TFSI to make the most of every breath. The benefits include:

• Improved power and torque, particularly through the mid-range
• Better support for Stage 1 and Stage 2 remaps, where the standard intake becomes a bottleneck
• A richer, more purposeful induction sound under hard acceleration
• Potential small gains in fuel economy when driven sensibly

Gains will vary depending on the rest of your setup, but the intake is widely regarded as one of the most worthwhile bolt-on upgrades for the K03-powered Mk2 TT.

Trifoam® Filter Technology

The heart of the system is Racingline’s Trifoam® filter, a triple-layer open-cell polyurethane foam developed using technology also seen in some Formula One engines. The layered construction traps fine particles while still allowing a high volume of air to pass through, giving you proper engine protection without choking performance.

It is a lifetime filter, meaning it does not need replacing in normal use. A simple clean every 20,000 miles (around 30,000 km) is all that is required to keep it in top condition.

Hand-Built in the UK

Every Racingline intake is built by hand in the UK using high-quality materials, with careful attention to fitment and finish. The fully-enclosed airbox draws cooler air from outside the engine bay, which is important because cooler air is denser and contains more oxygen, helping combustion. The enclosed design also keeps induction noise tasteful: noticeable when you push the car, but never droning during normal driving.

Sound Character

Expect a deeper intake note, a clearer turbo whoosh and a more audible blow-off when lifting off the throttle. It is a meaningful change over the muted factory sound, without becoming tiring on longer journeys.

Fitment

This kit is designed specifically for the Audi Mk2 TT 2.0 TFSI fitted with the K03 turbocharger. To make sure it suits your exact car, please use the vehicle lookup tool or check the Vehicle Fitment tab before ordering.

Installation is straightforward for a competent home mechanic, but professional fitting is strongly recommended to ensure all clamps, seals and mountings are secure for safe, leak-free operation.
