Product Description

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.5/8Y 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.

2.5 TFSI X34 Intake Installed

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.

Minimizing Unnecessary Filter Shrouding

034Motorsport focuses on optimizing every aspect of the intake system across a broad range of variables and compromises. A critical component of a high-flowing performance intake is the ability for air to flow around and into the filter. If the air cannot flow freely around the filter, it will be restricted from getting into it. Many aftermarket kits fit too large of a filter in an enclosure that cannot accommodate its size, thus choking the filter and reducing its overall flow. This often happens when a product is engineered for one variable at the expense of others. 034Motorsport conducted extensive tests and refined its development of the intake design to allow for maximum airflow surrounding the air filter, allowing for optimal airflow to, and through, the filter. The final result is the right size filter in the right size filter housing, creating maximum airflow and performance with OEM level filtering; the ultimate goal of any intake system. Be cautious of any intake that brags only of air filter size without taking into account the detrimental effects of shrouding the filter.

Performance Air Filter

The 034Motorsport Carbon Fiber Open-Top Cold Air Intake system houses a high-flow conical air filter with double-layer pleated cotton filtration medium. This air filter design offers increased flow through an enlarged filtration surface, while ensuring superior filtration.

OEM+ Fit & Finish

034Motorsport carefully selected the carbon fiber weave on the intake tube and upper airbox heat shield to match the factory carbon fiber engine trim found in the Audi TTRS & RS3 2.5 TFSI engine bay. The 034Motorsport Audi TTRS & RS3 4” Cold Air Upper Intake System was designed to fit like a factory part, and mates directly to the turbo inlet pipe and factory lower airbox to provide an OEM+ look.

Dyno-Verified Wheel Horsepower & Torque Gains

034Motorsport's engineering and development efforts were validated on multiple vehicles using our Mustang AWD Dynamometer to ensure that the 034Motorsport Audi TTRS & RS3 4” Open-Top Cold Air Upper Intake System provided substantial increases in horsepower and torque on both stock turbo vehicles and ones with upgraded turbo kits alike.
