Unitronic Intake System For B9 Audi S4 And S5 3.0 TFSI EA839 

Unitronic's all-new Carbon Fiber Intake System for the B9 3.0TFSI EA839 engines, found in the B9 Audi S4 and Audi S5, helps free up the intake restrictions of the OEM unit. It is engineered for seamless integration within the engine bay and improves the performance, look and sound of your vehicle.

 

Built with reinforced materials, high quality EPDM couplers and stainless steel hardware, this Intake System is more than capable of standing up to the rigors of track use or daily driving.

 

Airflow Optimization / Improved Flexibility

 

To validate its form through function; Unitronic engineers strategically used CFD to maximize its efficiency. Every aspect of the design was studied closely, iteration after iteration, until reaching the maximums governed by the laws of physics. The CFD simulations illustrate how well airflow travels through the system. The primary focus was to achieve laminar flow and minimal pressure drop in all areas of the design. The result of this is an increase in volumetric efficiency.

 

Unitronic high-quality EPDM silicone couplers offer a superior amount of flexibility over traditional silicone, while still offering the rigidity and strength needed to support high-powered 3.0TFSI’s. Unitronic’s engineers also 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's 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.

 

Proven Power and Torque Gains

 

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.
