034 Motorsport - X34 4" Carbon Fibre Open-Top Cold Air Intake System Audi TT RS & RS3 (8V/8S/8Y) - 034-108-1040

034 Motorsport Australia  - X34 4" Carbon Fibre Open-Top Cold Air Intake System Audi TT RS & RS3 (8V/8S/8Y) - 034-108-1040.

034Motorsport is pleased to present our X34 4" Carbon Fibre 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 Fibre Cold Air Upper Intake System.

Maximizing Airflow

034Motorsport engineers first created a CFD-optimized carbon fibre 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 fibre 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 fibre 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, 2.8inch 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 4inch 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 4inch 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 Fibre 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 fibre weave on the intake tube and upper airbox heat shield to match the factory carbon fibre 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 4inch 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.

Early non-US 8V.5 & 2025+ 8Y.5 Fitment Note

• Please note that very early non-US 8V.5 Audi RS3's and 2025+ 8Y RS3's come with a heat shield that is not compatible with the 034Motorsport Auxiliary Heat Shield supplied with this intake kit.
• The newer style OE heat shield can be purchased from an Audi dealer for under $100 USD. The OE part number is 07K 129 597 G. Once installed, the 034Motorsport Auxiliary Heat Shield can also be installed.
• The older style OE heat shield that is not compatible is shown in the photo below.
