42 Draft Designs 225 High-Flow Intake System is specifically designed for the Audi TT. The goal of 42 Draft Designs was to create a high quality intake with a clean look that truly delivers. The finished product exceeded everyones expectations. This High-Flow Intake System combines an oversized air filter with an engineered velocity stack in an accurately shaped heatshield. Precision machining, fabrication, and finishing methods are used throughout. The result is an air intake system that delivers serious gains and looks the part.
After being installed in the engine bay, the intake appears oversized and robust. On the road, this intake unleashes power and sound. The diverter valve is audible and the sound created by the velocity stack can only be described as vicious. Substantial power gains can be felt throughout the power band with no loss of low-end torque.
To understand how it works, let’s take a look at the construction. Starting at the MAF, an adaptor slides over the MAF while a silicone o-ring creates a seal. Our velocity stack slides through the heatshield and attaches to the MAF adaptor with an o-ring seal. The velocity stack represents the heart of the intake, drawing air equally from all sides and accelerating it to the opening of the MAF. An oversized air filter properly fits the velocity stack, minimally restricting airflow. The heatshield represents the backbone of the intake, holding the components together, mounting to the engine bay, and shielding the filter from engine bay temperatures.
The entire system assembles and installs with perfection thanks to the extensive craftsmanship used to create each component. The MAF adaptor and velocity stack are CNC machined from 6061 aluminum. O-ring grooves are utilized and contours follow the OEM MAF flange. The heatshield is constructed from laser cut 304 stainless steel. Each piece is fitted and TIG welded on precision tooling to assure accurate fitment. The heatshield is finished with a satin black powdercoat and stainless steel hardware is used to assemble the components. Your Audi TT never had it so good!

This thing is beautiful, just really well made and comes with everything you need to install it. It does growl a little more than just a K&N filter but that's a good thing.
The only downside was 42 draft designs cutter was out of service so it took longer than usual to deliver. That's right 42 draft designs cuts these per order! You might be wondering how I know their cutter was down - because Etek tuning's staff kept me up to date multiple times. Really nice to know your not just aneed order number. I'll be ordering again.

I purchased this intake for my 2003 Audi TT 225. Only other mod so far on the car is the Forge 008 DV. The intake is very well made and the instructions are clear and user friendly. Combined with the Forge DV it definitely gives you that swoosh sound. However, there is no hp gains if your car is stock. In fact you may actually feel a loss in hp. In order to take full advantage of the intake I believe you need to get a remap, and exhaust.
