The AEM 21-750 Performance Cold Air Intake System produces horsepower and torque gains by replacing your vehicle's restrictive factory air filter and air intake housing. This air intake system was designed, tuned and dyno-tested to fit specific Audi A4 and A5 models. Air enters the system through an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration and performance. The air filter is located in the original air box location and can optionally be protected by an AEM embossed heat shield which is designed to reduce intake air temperature and increase horsepower. This air intake system was developed to accommodate the engine's factory emissions control devices including the mass air flow sensor. The tapered cylinder shaped AEM Dryflow air filter is made from an oil-free, synthetic filter media that can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions). The air intake system is easy to install with commonly available tools and it is backed by AEM's Lifetime Limited Warranty. Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal.

Definitely sweet but good mixed
Flavor Name: Vanilla, Size: 30 Servings (Pack of 1)
The vanilla would be too sweet on it's own for me but with strawberries and spinach it's perfect.

Horribly ‘weird’ sweet flavor
Flavor Name: Vanilla, Size: 30 Servings (Pack of 1)
Horrible taste - synthetic sweetness than destroys my shakes. I bought Thorne because of its high quality but this is one of their products that won’t work for me. I’m struggling through the jar because it’s too expensive to waste. Using cacao powder, cinnamon & cardamom to try to tone down the overwhelming ‘sweet.’

Absolutely Great Stuff
Flavor Name: Vanilla, Size: 30 Servings (Pack of 1)
The vanilla flavored Protein Powder has to be the Best tasting Protein Powder Ever. Literally delicious. Product satisfies your appetite while supplementing your body with needed protein and nutrients. Combined with gym workouts I’ve noticed firmer muscles. A nice noticeable improvement.

It's a thing...
Flavor Name: Vanilla, Size: 14 Servings (Pack of 1)
I am probably the most skeptical person when it comes to supplements. I’ve tried so many over the years and honestly… most of them felt like a waste of money or just hype.
But I have to say—this combo has completely surprised me.
I’ve been consistently using Thorne protein and creatine, and within a few weeks I started noticing real changes. Not just how I feel, but how I look. My shoulders especially are looking more defined, and I feel stronger in my workouts without feeling jittery or weird like some products can make you feel.
What really stands out to me is how clean and simple it is. No bloating, no heavy feeling, no unnecessary extras—just something that actually supports what I’m already doing.
I also love that it fits easily into my routine. I take my creatine with my morning coffee (super easy habit), and I’ve been doing a protein shake after workouts which has helped a lot with recovery and keeping me on track nutritionally.
I’m currently in a calorie deficit getting ready for a trip, and this has honestly made it feel doable without feeling depleted.
If you’re someone like me who is hesitant about supplements, I’d say this is the first time I’ve actually felt like something made a noticeable difference.
