The OEM intercooler is made from plastic end tanks that are crimped onto an aluminum tube/fin core that is 4 inches thick (105mm core width) and is 5 inches in height (127mm). This may be enough to keep IAT's in check on a completely unmodified / stock vehicle, but once users to start increase power through bolt-on modifications, tuning, and built engines, the OEM intercooler will become the Achilles Heel of the system with IAT's skyrocketing out of the optimal range and drastically lowering the performance capabilities of the vehicle. Enter CSF with their stepped core design, bar/plate high performance N54 intercooler. This "drop-in fit" intercooler, which requires no modifications to install, has a bottom / larger section that is 5.5in thick (140mm) with a front face that is massive 8.25in tall (210mm). Made from CSF's industry exclusive rounded bar/plate core design. The rounded front face of the cooling bars allows for better airflow into the core. Airflow hits the core surface, and rather than scattering like it does with hitting the face of a flat bar that all competing products have, it travels around the face of the round bar and into core for much better performance than both the OEM design (flat face) and all other aftermarket competitors (all have flat face tubes or bars). A huge improvement over the OEM unit, and enough to handle even the most advanced N54 engine builds. Good for 1000hp no problem!Shipping Notes

A little snug on the thighs
Size: Medium, Color: Multicoloured G (5-pack)
Super comfy, soft and thin. For reference, I'm 5'6", 135, athletic build. I bought medium. I almost returned them because I thought they were a bit too snug on my thighs, and my thighs are not large at all. I was concerned about panty lines under snug clothing. But, because they're thin, I figured they would probably stretch, so I kept them. So far, I've only worn them under a night shirt, but they're super comfortable and they dont ride up at all. Very nice, but if your thighs are a little thick, you probably won't like them.

Functional + Sexy
Size: Small, Color: Multicoloured E-(5-pack), Size: Small, Color: Multicoloured E-(5-pack)
Not only do these feel good, my husband can’t keep his hands off me. They fit so good and are soft. I change into these to sleep but also just use them as shorts to wear around the house. They’re comfortable and don’t slide around. I got a size small and I’m 100lbs.

Finally!
Size: X-Large, Color: All Black D (5-pack)
Finally, comfortable underwear that don’t end up giving me a wedgie. I have a round booty and most cuts of underwear end up shifting as I walk and sit. The hem of the underwear comes right under my cheeks and the lightweight material ensures there’s no panty line and no shifting to where I don’t want them! I’m definitely purchasing more.

Very thin, still comfy but very thin material. Super soft though. I've worn and washed and they have held up but I won't be repurchasing bc these are so thin

They’re fantastic!!!!
Size: X-Large, Color: Multicoloured E-(5-pack)
My clothing size is 16/18 and XL. Even though Amazon suggested a size XXL, I ordered my normal XL and they fit perfectly.
The fabric for this style is 92% bamboo viscose and is amazingly soft and almost silky feeling. I had ordered a different boy short in this brand but they were 80% bamboo viscose and the fabric was significantly heavier. I returned those and ordered these.
