Significant effort went into developing this comprehensive performance intake solution for the turbocharged 3.0 TFSI engine found in the latest generation B9 Audi S4/S5. Subsequently, the X34 Carbon Fiber Full Intake System offers discerning enthusiasts measurable increases in horsepower and torque, sporty induction and turbocharger sounds, and a beautiful carbon fiber airbox and inlet pipe design.
Throughout the development process, multiple designs were modeled, prototyped, and tested – all to ensure that the X34Â Carbon Fiber Full Intake System delivers measurable performance benefits and superb fitment. The result is a partially-enclosed airbox which uses the factory fresh air inlet duct and heat shield, while housing a massive 5″ inlet conical air filter, and a matching CFD-optimized carbon fiber filter tube.
The X34 Carbon Fiber Full Intake System for B9 Audi S4/S5 was engineered with performance in mind, and is a free-flowing replacement for the factory airbox and turbocharger inlet hose. As the development of this intake progressed, the X34 Carbon Fiber Full Intake System yielded measurable reduction in pressure drop at the turbo inlet compared to the factory airbox, with a corresponding increase in horsepower and torque throughout the powerband.
Test Conditions:Â Dyno testing was performed on a stock 2018 Audi S4 3.0 TFSI using 91 octane fuel, piggyback, and 034Motorsport High Flow Cat.
