034Motorsport X34 4" Carbon Fiber Open-Top Intake System for Audi TTRS & RS3

Note: Carbon Fiber Air Duct Not Included With This System

034Motorsport is pleased to present our X34 4” Carbon Fiber Open-Top Cold Air Upper Intake System for the 2.5 TFSI EVO engine found in the 8S Audi TTRS and 8V.5 Audi RS3!

034Motorsport’s engineers spent extensive effort to develop a cold air intake solution for the TTRS and RS3 that yields horsepower and torque gains over the well-designed factory airbox. During the development process, many iterations were designed, prototyped, and tested, which resulted in this beautifully-manufactured Carbon Fiber Cold Air Upper Intake System.

DESIGNED FOR MODULARITY

034Motorsport engineers dissected the factory intake system, and identified the key weak points that it had for high performance flow. During this dissection, it was found that the largest restriction was the filter membrane, and the accompanying plastic accordion hose that runs to the turbocharger. The factory lower air box and fresh air duct, however, with some modifications, were found to be suitable for most stage 1 and stage 2 setups.

This drove the modular design that the X34 Evo intake systems all share, where the upper air filter system can be used both with the factory lower airbox and fresh air duct, and with the 034Motorsport X34 lower intake box and fresh air duct. This allows for the end user to purchase individual components to eliminate the largest flow issues, while still having a path to upgrade to higher flow and performance.

MAXIMIZING AIRFLOW

034Motorsport engineers first created a CFD-optimized carbon fiber intake tube, which is a direct, high-performance replacement for the plastic factory accordion hose. Using CAD software and 3D scanning technology, 034Motorsport was able to optimize the cross-sectional area of the intake tube while being mindful of space constraints. The resulting part is a functional work of art - maximizing performance given the factory space constraints and featuring smooth transitions that ensure optimal airflow to the turbo inlet.

MINIMIZING INTAKE AIR TEMPERATURE

To ensure that the 034Motorsport X34 Open-Top Cold Air Upper Intake System draws in cool, dense air, the system includes a fully enclosed carbon fiber heat shield to replace the upper airbox as well as a stainless steel heat shield to block heat from saturating the intake tube. The upper carbon fiber heat shield bolts to the factory lower airbox, allowing the high-flow conical filter to breathe cold air from the factory inlet duct before the radiator. The stainless steel heat shield bolts to the stock intake tube mounting point and to the back of the head, preventing the high temperatures from the exhaust header and turbo from radiating directly at the intake tube. Both heat shields work together to minimize pre-turbo intake air temperature.

4" DIAMETER FOR MAXIMUM PERFORMANCE

034Motorsport engineers identified a serious bottleneck in the factory intake system. The factory, 2.8” turbo inlet size, which necks down even smaller throughout the unit, is by far the largest restriction in the intake system after a performance filter system is installed. Many aftermarket companies, including 034Motorsport, have solved this issue by increasing the turbo inlet diameter, thus warranting an intake that supports the added flow gain. The 4” diameter intake kit is designed to support upgraded 4” turbo inlets that can be used on factory, hybrid, and full frame turbochargers. It has been validated that this intake works with the majority of aftermarket inlet options, but has been optimized to work with the upcoming 034Motorsport 4” turbo inlet.
