The Engineering team at ECS Tuning has spent countless hours in the development of the exclusive Audi B9 RS5 2.9T Kohlefaser Luft-Technik (Carbon Fiber Air Technology) Cold Air Intake System. This intake was precision engineered using state of the art laser scanning, flow bench testing, and 3D CAD technology to combine factory-like fitment in your engine bay with increased engine performance.

This intake is crafted of high quality hand laid carbon fiber with a fiberglass interior layer to achieve world class appearance and durability while resisting the performance robbing effects of heat soak. The turbo inlet hose is crafted of a high quality 4-ply silicone to achieve increased durability and resistance to collapsing.  We also include a bellmouth (velocity stack) filter flange inlet to reduce turbulence and maximize flow.

This intake has been subjected to rigorous real world testing with verified performance gains on our in-house flow bench. At -12.0 in H2O test pressure, the stock intake had a flow rate of 362.0 CFM and our ECS intake had a flow rate of 462.7 CFM - an increase of 27.8%!  The increase in turbocharger spool noise during heavy acceleration is an enthusiast's dream, giving hint to the added performance without being too intrusive. The end result of all of this effort is an intake system that combines fitment, quality and performance into one stunning package that will make a statement in your engine bay.  

The ECS Tuning Kohlefaser Luft-Technik Intake System features:

  • Specifically crafted to fit Audi B9 RS5 2.9T engines, using stock mounting locations
  • Carbon Fiber lid, carefully contoured to allow the smoothest flow path
  • 4-ply silicone turbo inlet to hinder collapsing
  • Powder Coated aluminum heat shield
  • 3" conical hi-flow reusable air filter; featuring 8 ply cotton gauze construction and a bell mouth inlet to minimize restriction while maximizing filtration efficiency
  • Stainless steel hardware & hose clamps for exceptional corrosion resistance and durability
  • Broader and smoother torque curve for an enhanced driving experience
  • 27.8% increase in flow rate compared to the stock intake
  • No modifications required, fully reversible installation
  • Complete install instructions provided!

Settle for nothing but the absolute best with ECS Tuning's Kohlefaser Luft-Technik Intake Systems. 

For additional help with heat protection, ECS Tuning has created pre-cut DEI Reflect-A-Gold to apply directly to the intake heat shield. Check out ES3610302 for more information.

Exceeds performance expectations of OEM fluids
Size: 5 Quart Jug
You know I didn't think it would work as well I've heard all these horror stories but you know what this works better than the factory CVT fluid this stuff is great this is amazing be very careful to get your levels correct that goes without saying with any transmission but once you do that this fluid is amazing I have a better performance than when I had the new transmission I serve my CvT 35 to 40,000 miles I'm using it in a 2018 Mitsubishi outlander base model and I'm also running Yokohama geolander 015s on it. If you worry about tires for you Mitsubishi or any vehicle. I'm going to say you'll call when you lander whether it's a car or crossover or an SUV this tire is amazing it's best all around tire and your rain traction is phenomenal

Good Stuff!! All low speed shudder is gone.
Size: 5 Quart Jug
I have a 2020 Nissan Altima SL 2.5l and Nissan is VERY specific about using ONLY NS3 transmission fluid. There are only a couple NS3 transmission fluid manufacturers...Nissan NS3 (Manufactured by Idemitsu), Idemitsu (a little cheaper than Nissan dealer), Triax, and Mannol (works good too). Seeing as Nissan is still using Jatco CVT transmissions which are known to be very troublesome, and very expensive to replace I wouldn't try any of the so-called "universal" transmission fluids just to save $50 and end up replacing a $6000 transmission. The Triax fluid seems to work very good in my car. I don't feel the shutter that I normally feel when driving slow and need to accelerate. The shudder is completely gone and operating smooth. The old fluid had 50k miles and it was very dirty but didn't smell burnt. I ended up doing 2 - 3 1/2 quart changes with 200 miles between the first and second change. I plan on doing another 3.5/4 quart change every 15k miles since there is no way to completely drain the 7.4 quarts of transmission fluid. The first change, only 3.5 quarts drained from the pan.

Quality fluid for half cost in Mini CVT.
Size: 5 Quart Jug
Used in the cvt transmission in my 06 mini cooper. The fluid requirements recommended by BMW are met with this fluid. Fluid improved shifting and performance at half the cost of traditional BMW OEM fluid.

This CVT Fluid worked perfectly in a 2018 Chevrolet Spark.
Size: 5 Quart Jug
This fluid is fantastic. I bought a 2018 Chevrolet Spark with 30K miles and had a bad transmission shudder. Drained the transmission, cleaned-out the pan, and replaced the filters. Old fluid was black and this is a clear green. I loved the jug as it had a pop-up spout that was small and easy to pour, and the jug has a side handle. Transmission works great and the shudder is gone. I plan to change the filters and fluid again after 1K miles. This fluid is well worth the money!
