Description
 

Immediately following the release of 42DD's TT 225 High-Flow Intake requests began pouring in for additional fitments. The VW Mk4 community seemed to shout the loudest, especially after learning that the TT intake is not a direct fit in the Mk4 1.8T. Although visually similar, the Mk4 1.8T intake required a complete re-design. Simply modifying the TT intake to fit the Mk4 was not an option. With our challenge well known and under a bit of pressure we set forth to tackle the fitment and create an intake that truly performs. Once again the finished product exceeds our expectations.

Our Mk4 1.8T 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.

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 waterjet 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.

Installed in the engine bay, our intake appears oversized and robust. On the road, our 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.
