034Motorsport is pleased to present our X34 Carbon Fiber Closed-Top Intake Bundle 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 complete cold air intake solution for the TTRS and RS3 that yields airflow and pressure drop gains over the well-designed factory airbox, which can lead to higher horsepower and torque gains in applications that require higher airflow, like upgraded turbos. During the development process, many iterations were designed, prototyped, and tested, which resulted in this beautifully-manufactured Carbon Fiber Cold Air Intake System that flows better than no intake at all.
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.
To ensure that the 034Motorsport X34 Closed-Top Cold Air Intake System draws in cool, dense air, the system includes a carbon fiber upper airbox, to replace the factory part, and also a stainless steel heat shield to block direct radiant heat from saturating the intake tube. The upper carbon fiber airbox 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 parts work together to minimize pre-turbo intake air temperature.
The 034Motorsport Carbon Fiber Closed-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.
034Motorsport carefully selected the carbon fiber weave of the intake tube and upper airbox to match the factory carbon fiber engine trim found in the Audi TTRS & RS3 2.5 TFSI engine bay. The 034Motorsport Audi TTRS & RS3 Closed-Top Cold Air Intake System was designed to fit like a factory part, and mates directly to the factory mounting provisions to provide an OEM+ look.
Pressure Drop is the difference in ambient air pressure and the air pressure measured at the turbo inlet across the engine's rpm range. The higher the pressure drop at any given rpm, the more restrictive the intake system is, reducing airflow.
| Intake Configuration | Chart Color |

| X34 Open Top CAI w/ X34 Lower Airbox and Fresh Air Duct | Green | -2.43 psi |
| X34 Closed Top CAI w/ X34 Lower Airbox and Fresh Air Duct | Yellow | -2.52 psi |
| No Intake (Open Turbo Inlet) | Blue | -2.50 psi |
| X34 Closed Top CAI w/ Stock Lower Airbox | Gray | -2.61 psi |
| Stock Intake | Red | -2.77 psi |
034Motorsport's engineering and development efforts were validated on multiple vehicles using our Mustang AWD Dynamometer to ensure that the 034Motorsport Audi TTRS & RS3 Cold Air Intake System provided substantial increases in horsepower and torque on both stock turbo vehicles and ones with upgraded turbo kits alike.
