CSF has over 5 decades of experience manufacturing radiators. So when it comes to keeping your engine cool and your 1M/135i/335i running at its best, a CSF High-Performance All-Aluminum Radiator is the obvious choice. Designed to perform on the street or at the track, a performance radiator is a must-have for both high horsepower builds as well as race vehicles which need added cooling performance in motorsports environments. This radiator features a 2-Row core with CSF's exclusive B-Tube Technology: Unlike a regular oval shape "O" type radiator tube, CSF uses a specially engineered tube in the shape of a "B". These "B-tubes" are carefully formed and then brazed over the seam to seal. CSF is able to use thinner and lighter aluminum material (with better cooling efficiency) because this design is actually stronger than normal "O" shape tubes that are welded. The design (inlet in the middle of the tube that is seam brazed) increases the heat transfer surface area of the tubes by approximately 15% over regular tubes - producing the efficiency of two smaller tubes vs. one large tube within the same space criteria. With "B-tubes" you are able to get "dual liquid laminar flow". CSF also uses ultra efficient multi louvered fins that are carefully and precisely aligned to maximize airflow through each radiator core. Fin specifications are carefully measured and calculated for each application, and tested for maximum heat rejection efficiency in our wind-tunnel lab.Shipping Notes

A Great Pair of Small PC Speakers
Size: 1 Pair, Color: Silver, Size: 1 Pair, Color: Silver
These are great little pc speakers. They hookup easily, give off great sound, have an in line cord volume control and look great on the computer desk. The only thing missing is an on/off switch so you have to detach the usb to turn off the power, if desired, when the PC is on. My usb port is on the front of my desk top so it's easy.

Don't by used from amazon
Size: 1 Pair, Color: Black
Bought them used (don't do it plz) and they work well but at times I notice a hissing sound that always happens when I'm not playing any audio from them, and then there's times where there's no hissing sound. It's not the loudest but it can get kind of annoying. I'm sure it's because I bought them used but oh well, saved a few bucks and this is what I get. Other then that though the actual sound quality of the speakers is crazy good for the money. Speakers have nice weight to them and really decent bass to em as well. Just gotta give it 3 stars since Amazon didn't find it necessary to
1. Didn't clean the product before shipping so that it was in a presentable state, came to me hella dusty
2. Idk if anyone actually did long enough testing on this product when it got sent back, or else they would've fixed the hissing problem. I assume that was why it was sent back in the first place
3. Box was terribly packaged. No bubble wrap what so ever, the box the actual speakers were in also had nothing keeping them safe from getting smacked around during shipping. Multi billion dollar company can't even go the extra mile for the people who are paying them and keeping them in the business.

Perfect!
Size: 1 Pair, Color: Black
My husband wanted old-school plug-in speakers that had quality sound. These fit the bill and at an excellent price! They function exactly how the older speakers did, plug in and enjoy! No need to mount but you can if you wanted to. Easy to use and they have great volume. He does music making and video game development, so he needed the sound quality.

Unbelievable Performance!
Color: Black, Size: 6 Feet, Style: 5-Pack, Color: Black, Size: 6 Feet, Style: 5-Pack
I didn't expect such a great performance by these charging cables since even they are not brand. Decent price for a bunch of solid and plenty long charging cables. These are in high quality and charge fast the cell phone. Don't waste your money buying at the stores or the branded one.

Good reliable cable
Color: White, Size: 6 Feet, Style: 1-Pack
Very good quality cable works as expected with no issues at all. Easy to clean seems more durable than the OEM cable from Apple. Well pleased- I have several.
