Audi C8 RS6/RS7 High-Performance Twin Intercooler Set - Raw Billet. The CSF by PWR C8 RS6/RS7 Twin Intercooler Set features Formula-1 grade cores which offer the greatest reduction in IATs and help eliminate heat soak. The Billet Aluminum construction offers the greatest strength and durability possible.

CSF teamed up with leading VAG specialists from Southern California, Pacific German, to bring this critical intercooler system to market, unlocking the full potential and increasing power goals of the new C8 platform. With the OEM intercoolers, the new C8 platform starts to exhibit heat soak and run-away increases in IATs, which then triggers the ECU system to pull timing out of the engine and subsequently lowers performance.The most important feature of the CSF by PWR RS6/RS7 Intercooler System is the Formula-1 grade intercooler core. CSF's strategic relationship with PWR has allowed the inclusion of this core, which is unlike any other available in the performance aftermarket. Featuring two rows of rolled cooling tubes with inner fins, these cores make for the most efficient intercoolers available. Because of this, they are able to eliminate heat soak and lower IATs much more efficiently than traditional Bar & Plate or Tube & Fin designs. This gives us maximum performance for extended periods of time under demanding driving conditions and for vehicles with increased power levels through modifications and tuning. As with our other products produced through our PWR partnership, our new RS6/RS7 Intercoolers feature 100% TIG-welded machined billet aluminum end tanks vs. the OEM crimped cast aluminum end tanks. This feature is not only aesthetically pleasing, but is also stronger for longevity and durability on high-performance vehicles. The CNC machined billet end tanks are ready to withstand increased boost pressures from higher performance tunes, as well as upgraded turbochargers.With the enthusiasm that RS6/RS7 customers have for their vehicles, the platform is already the coveted 1000hp mark and the CSF intercoolers are one of the critical components in reaching these power goals.The CSF #8194 comes in a raw billet aluminum finish. Also available in Thermal Black Heat Dispersion (CSF #8194B).

Relaxed Fit Linen Blend Button Down Shirt
Size: Large, Color: Light Beige, Size: Large, Color: Light Beige
I like this shirt and it actually looks better than it does in the attached photo. The shirt is 55% linen and I took the photo without ironing because I wanted to show that this shirt is better than many linen shirts when it comes to wrinkles. In fact, I can steam the wrinkles out and don’t need to drag out the iron. The shirt is cool and comfortable. I like that you can use the draw string waist to make it more fitted. The button holes are a little small, which makes it harder for those of us who have arthritis to use. I will just leave most of the buttons fastened and slip the shirt over my head. It seems very well made. I looked it over carefully and did not find any loose threads or missed stitches. I think this is a good value.

Cute summer top
Size: Large, Color: Light Beige, Size: Large, Color: Light Beige
Cute and comfortable linen blend shirt that’s perfect for summer. The fit is relaxed without looking oversized or sloppy, which I really like. I usually wear between a large and extra large depending on the chest area, and I ordered the large based on the size chart. It fit correctly according to the measurements, but I personally think the extra large may have been a little more comfortable for me through the bust. For reference, I’m around a 33-inch waist and a 42C bust. The light beige color is really pretty and easy to style with denim jeans, jean skirts, or sandals for a casual summer look. Since it’s a lighter-colored cotton-linen blend, you’ll want to wear the proper undergarments underneath depending on your skin tone, which is pretty normal for linen-style fabrics. I also love the adjustable cinched waist because it gives the shirt a more flattering shape without making it tight. Overall, it’s a beautiful lightweight top with a nice relaxed fit, and I definitely recommend it.

Linen/Cotton Blend; Machine Wash Cold, Lay Flat or Hang to Dry; Real Buttons
Size: Medium, Color: Light Beige, Size: Medium, Color: Light Beige
Amazon Essentials Women's Relaxed Fit Linen Blend Wide Sleeve Shirt with Adjustable Tie Waist Review: I got this for my daughter mostly (we trade clothes back and forth), and she finds it very comfortable and flattering. For reference, her measurements are about: 39 inches around the bust 35 inches around the hips/stomach  And 42 inches around the bottom   I ordered her a Medium, and it fits her very well, but it's on the edge of being big. If she lost a little weight, it might seem big but fit me a little better, but it fits her very well now. It's a very breathable fabric, and the cut is flattering. It is a little see through, not majorly, but she says she will probably wear it with a white or nude tank top as an underlayer, possibly with a bra too, but at that point it might be too hot for a summer outfit. It could be dressed up or down and would pair well with a skirt or jeans, with sandals or heels or cute sneakers. It could also be worn fully unbuttoned over a tank top, if one wanted. The buttons are real, and seem well-sewn. The collar is initially reluctant to stay open, but it will relax in time or one of us could iron it like that, but we're unlikely to, lol.   The only complaint she had was that when she goes to raise up her arms and hold them horizontally out in front of herself, the sleeves and shoulders become too tight across the back and up the arms, although this is a very common problem, unfortunately, with women's/girl's clothing. We'll have to live with it, but it will keep the shirt from being worn as often as it might have been. We're definitely happy for the natural fibers (a linen/cotton blend). We are both excited to wear and style it. I'll include photos.

Stylish & Comfortable Linen Blend Shirt with Great Fit and Durable Feel
Size: Small, Color: Light Beige
This Amazon Essentials linen blend shirt is a really nice addition to my wardrobe. The relaxed fit sits comfortably without feeling too loose or shapeless, and it drapes well on the body. The wide sleeves and adjustable waist add a stylish touch, making it look both casual and slightly dressed-up at the same time. The fabric feels good—light, breathable, and perfect for everyday wear. It has that easy, airy feel that works really well for warm weather while still looking put together. After the first wash, I was happy to see that the quality stayed the same. No noticeable shrinking, fading, or change in texture, which gives confidence that it will hold up well over time. Overall, it’s a simple but very flattering shirt that combines comfort, style, and good durability. Great for everyday outfits or casual outings where you still want to look a bit polished.

Sizing Varies, But an Amazing Tee if you get the right size!
Size: Large, Color: Navy
I ordered this in a size Large, my recommended size per Amazon and the size chart, it was so small through the underbust area that I could not wear it. I then ordered an XL and it is huge! The XL is too big everywhere, but especially through the bust! For your reference the bust line in the XL measures 42" pit to pit. I am going to try again to order a Large and see if perhaps I just got one that was sized incorrectly. This tee is so cute. I love the fit, the neckline, the slight flare at the hem. It's super cute and offers a great feminine look and feel. The material is amazing. Super soft, perfect non-clingy drape, opaque, lightweight . . . there's nothing not to love here!
