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.

I Smell Like a Gentleman Who Owns a Fireplace
Scent: Bourbon Oak, Size: 16 Fl Oz (Pack of 1)
The fragrance is warm, woody, and slightly sweet...that low amber note that smells expensive without trying to smell expensive, which, as we all know, is the actual expensive smell. My wife walked past me twenty minutes post-shower and said, unprompted, "You smell really good." I nodded like I had planned this. The lather is genuinely rich; squeeze a modest amount and it blooms into a thick, creamy foam that covers everything efficiently. The texture is silky rather than watery, which matters more than people admit. Watery body washes feel like rinsing off with slightly scented regret. This one feels intentional. It cleans, and your skin actually feels clean afterward, not just rinsed. And the moisturizing? I wasn't expecting it. No greasy film, no lotion-begging dry patches by midday. Just quietly softer skin that doesn't make a big announcement about it. Now, my honest gripe: the scent longevity has a ceiling. By mid-afternoon you're back to neutral. That's the gap between four stars and five for me. For daily freshness and an incredible morning window of smelling genuinely great, it absolutely delivers...but it won't carry you to bedtime. On value: 16 fl oz is decent, the lather is efficient so the bottle lasts, and the price sits in that sweet spot where you feel like someone who makes slightly elevated but still reasonable choices, which is exactly the vibe this entire product is going for.

Lathers great in a small amount!
Scent: Bergamot, Size: 16 Fl Oz (Pack of 1), Scent: Bergamot, Size: 16 Fl Oz (Pack of 1)
Lathers great for a small amount! A fair price for the amount and rich content. I just bought, used and love it. Definitely will purchase again. I love the sophisticated yet sensible smell doesn't overpower. In my perception it is a unisex scent as I am a woman and bought for myself.

Smells Like You Have Your Life Together
Scent: Bergamot, Size: 16 Fl Oz (Pack of 1)
Cremo Body Wash with Italian Bergamot, Neroli Blossom, and Fresh Vetiver smells far more expensive than it has any right to. The scent hits that sweet spot between fresh and refined. The bergamot gives it a clean citrus lift, the neroli adds a smooth floral edge, and the vetiver grounds it with a subtle, masculine depth that does not scream but absolutely speaks. The lather is rich and concentrated, so you only need a small amount. It feels more like something you would find in a boutique hotel than on a regular store shelf. The fragrance lingers just enough to be noticed without overpowering your cologne or filling the entire room. If you want to step out of the shower smelling like competence and quiet confidence, this one delivers. It is polished without trying too hard, and it makes everyday showers feel slightly upgraded.

A major upgrade from standard drugstore brands—sophisticated scent & better lather.
I have been a long-time user of standard body washes (think Old Spice, Axe, or Dove Men), but I kept seeing hype about Cremo and decided to see if it was worth the slightly higher price tag. After using the 32oz Spice & Black Vanilla for a week, I can confidently say this is a massive upgrade for your shower routine. ​Here is how it stacks up against the typical grocery store brands: ​1. The Scent is on another level: Most cheaper washes smell like generic "Sport" or "Ocean" cologne. This scent is much more complex and earthy. ​Top Notes: It starts with a sharp, spicy kick (that's the cardamom). ​Finish: It settles into a smooth, warm vanilla and tobacco scent. It smells more like a high-end department store fragrance than a soap. ​Staying Power: The scent actually lingers. If you shower in the morning, you will still catch subtle hints of the warm spices for a few hours, which pairs really well with woody colognes. ​2. Performance & Feel: The consistency is thicker than what I'm used to. You only need one solid pump to get a rich lather with a loofah. Crucially, it rinses clean without leaving that "squeaky" residue that dries out your skin, but it also doesn't leave a slick oily film like some ultra-moisturizing washes do. It hits a perfect balance. ​3. Value: The 32oz bottle is substantial. Because the gel is concentrated, I expect this bottle to last 3-4 months easily, making the cost per ounce very reasonable compared to buying smaller bottles of cheaper stuff every few weeks. ​Pros: ​Sophisticated, "grown-up" scent profile. ​High-quality pump (sturdy, doesn't clog). ​Non-drying formula is great for colder months. ​Cons: ​Potency: The scent is strong. If you are sensitive to fragrance or prefer unscented products, this might be overwhelming. The bathroom will smell like it for a good 20 minutes after you're done (which I enjoy, but keep it in mind). ​Verdict: This bridges the gap between basic hygiene and luxury grooming. If you are tired of smelling like "Blue Sport" and want something warmer and more refined for the fall/winter, this is absolutely worth the switch.
