Unitronic® is pleased to release its Carbon Fiber Intake System for the B9 Audi® S4 and S5 equipped with the single turbo 3.0 TFSI engine. This Carbon Fiber Intake System is a direct bolt-on upgrade which is designed to optimize airflow, improve throttle response, enhance turbo induction sounds, and increase power, gaining +10 HP & 4 LB-FT. It also provides seamless integration, perfect fitment and an aggressive carbon fiber presence in the engine compartment.
Consistent with all of its performance products, Unitronic utilizes only the latest industry leading tools, equipment and computer aided design software that are packed with the latest technology from our technology partners at Creaform® and Stratasys®. These tools and technology help to achieve a design that not only optimizes airflow and speed, but also eliminates airflow restrictions that are present with the factory components, while fitting within the engine bay constraints.
At Unitronic, development begins with setting the objectives; performance, efficiency, aesthetics and quality. Operations start with 3D scanning the 3.0 TFSI engine bay and OEM components with it’s in-house 3D scanner. Once 3D scan data has been collected and processed, Unitronic Hardware Engineers then interact with the 3D models to identify fitment constraints, mounting locations, other component locations, etc. to ensure the final product fits perfectly within the “envelope”.
As the initial designs develop; evolution begins with rapid prototyping, utilizing its in-house Stratasys 3D printer. Within hours, Unitronic Engineers are able to have a complete working printed prototype, allowing for test fitments to be performed on the vehicle, functional testing to be completed, and flow data collected to further validate the designs.
Unitronic engineers studied what the engineers at Audi® had intended for the stock unit. The first aspect considered, was how to make it more efficient, yet effective. The result is a design that exhibits smooth volumetric transitions. Every facet of this design is effectively executed for form and function.
Unitronic Engineers further validated designs to ensure that the Unitronic Carbon Fiber Intake System developed more power using its in-house MAHA Chassis Dynamometer. Unitronic was able to measure considerable horsepower and torque gains in tuned vehicle applications.
Our pursuit for perfection is applied even in the most minute areas of product design and in this case, Unitronic identified that allowing for ample tolerance for engine movement on an item that is both affixed to a dynamic engine and a rigid chassis. Rather than using traditional silicone for its hose connections, this Unitronic Carbon Fiber Intake System uses a high-quality, extremely durable EPDM material for its couplers.
This offers a superior amount of flexibility over traditional silicone, while still offering, with its clever design, the rigidity and strength to be highly reliable on the 3.0 TFSI engines. Taking the design and engineering one step further, Unitronic engineers created a design that allows for smooth, laminar airflow on the inside walls, while maintaining flexibility through the means of a non-collapsing structural rib profile. Unitronic EPDM couplers are designed to perfectly align with the bead rolls on the carbon fiber tubes, to ensure a perfect and seamless connection; hose clamp guides ensure perfect alignment.
This sectional of the coupler shows a 3D CFD representation of airflow across the ribbed profiled construction. The ID of the ribs matches the ID of the interconnecting tubes for a seamless transition. As a result, even under varying conditions where flexing and stretching happen, airflow remains uninterrupted.
The Unitronic Carbon Fiber Intake System offers superior fit and finish with a direct bolt-on fitment, retaining the factory mounting locations and simplifying the installation process using our very own mounting grommets. Available as a stand alone item, our 6" Tapered Cone Air Filter (UH007-IN4) offers optimal airflow for most applications while protecting the turbocharger and engine from debris and air particles that may be encountered during everyday and spirited driving.
