Performance Gain: 11-16hp, 12-17ft-lb At The Wheels
The Audi B9 RS4/RS5 Eventuri intake was developed to give less restrictive airflow to the turbo whilst maintaining low inlet temperatures. The RS5/RS4 engine bay becomes heat soaked very quickly so simply having an open cone system would result in better airflow but with higher inlet temperatures. We therefore completely re-engineered the inlet track from the turbo inlet pipe to the front grill with a highly efficient sealed system. The restrictive stock airbox and flexible plastic inlet pipe have been replaced with a Venturi filter housing and a duct system with smooth transitions. Furthermore, by removing the convoluted stock inlet pipe and replacing it with our one-piece Venturi housing and solid tube, the airflow is much smoother as it enters the turbo inlet tube. The resulting performance gains and aesthetics are industry leading for this platform.
The Eventuri Difference
The B9 RS4/RS5 Eventuri system uses our Patent Pending Carbon fibre Housings with our bespoke Gen-2 filter which provide an aerodynamically efficient airflow path from the filter to the inlet tubes. Not just another cone filter with a heat shield but a unique design which invokes the Venturi effect. You can read more about the housing design and how it works HERE
The Eventuri B9 RS4/RS5 intake system consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards. Here are the details for each component and the design ethos behind them:
Each intake system consists of:

Purchased an exhaust for our 2000 Porsche Boxter S. What a fantastic product. Sound is amazing, and the car does indeed feel a step faster. Customer service follow up was amazing and am already shopping for the next performance upgrade for our 986 Fabspeed manufacturers. Highly recommended.
I purchased an exhaust system from FS over 2 years ago for my 997.2 C2S. The sound was just glorious and I was pleased with the purchase. Unfortunately, last month, a weld broke on one of the mufflers and I needed it repaired. After one phone call, I could tell this company takes customer service seriously. In a world of voice mail and self help, Everyone I spoke with was very professional. In fact, Brian Jamison proactively called me 2 times and sent follow up emails, to keep me updated during the process. Fabspeed completely warranted their work and sent me 2 brand new mufflers with an improved design. (Not only is the engineering more simplistic but the welds and workmanship are gorgeous. They aligned perfectly and went on in minutes.) Very impressed with this company, its people, and it's product.
Firstly, I want to start off by complimenting the customer service I received from Fabspeed. I worked with Gary from the beginning and he was nothing but helpful, answering all of my questions and helping me understand exactly what I wanted for my car. Once I picked out what I wanted, the ordering process was easy and the package came FAST! Install was easy and the end results were AMAZING. Simply installing their headers took my car from sounding cool to COOL!! I get so many compliments on how the car sounds and everyone is blown away to learn that I only installed headers with no tune. I could not be happier with the result, especially at a relatively low cost. THANK YOU FABSPEED!! Can't wait to work with this company again in the future.
Great team and outstanding products. Thank you DJ for all your help getting my Porsche 991.1 all setup and sounding amazing.
i have made the installation of the FABSPEED Sport cats and Sport headers on my 2017 Porsche 991.2 Carrera 4 cab at my Porsche Center yesterday and iam very satisfied. Still quiet when the PSE is off and very loud in sport and sport+ mode, i like so much the backfire who are this time stronger and the turbo noise who is more noticeable. Iam very happy of the sound a lot better of the original one, thanks you FABSPEED
