BMW F3X/F2X B58/B48 Triple-Pass Heat Exchanger w/ Rock Guard - Silver. Significantly reduce Intake Air Temperatures (IAT) for Maximum Performance (with Faster Heat Soak Recovery) on your B58/B48 Powered BMW with a CSF Heat Exchangers.

As the 3.0 Liter B58B30M0 (1st gen B58) turbo engine platform continues to be developed by the high performance industry and more power is extracted from the engine, CSF's high performance heat exchanger for the BMW B58 engine will be a critical component to keeping the vehicle charge air cool, and out of limp mode. The CSF BMW B58 upgraded heat exchanger for F-series vehicles will be especially important to install in upgraded turbo applications and/or vehicles running high performance tuning software.; The original OEM B58 heat exchanger is a 1-row unit that is 27mm thick. In comparison, CSF has used its industry-exclusive world's largest 2-row core (68mm) with CSF's B-Tube technology. A unique tank design allows the larger CSF core to still fit into the OEM cooling system housing. Another critical feature of the CSF BMW B58 high-performance heat exchanger is its unique triple-pass flow design. The water traveling through the upgraded heat exchanger flows through the radiator three times before exiting the cooler and flowing back into the manifold charge cooler. This ensures that the outlet water temperature of the heat exchanger is the absolute lowest it can be. The OEM design, as well as more expensive aftermarket designs, all have single-pass flow structures.; The CSF #8131 comes in a Polished Finish. It is also available in a Satin Black Finish for OEM+ look (CSF #8131B).

Busted spring on one side....
Color: Black, Size: 28-70"W x 48-120"H (Pack of 1), Color: Black, Size: 28-70"W x 48-120"H (Pack of 1)
I would have given it five stars except for the fact that 1) the instructions that come with it are miserable so you will definitely want to refer to the photos they have in the advertisement here, and 2) it appears that one of the vertical poles has a busted spring and I literally had to stuff some socks underneath it to make it hold. Definitely an eyesore, so I'm not thrilled about that. With that being said, I'm in an apartment and I don't want to drill in the walls to hang a curtain rod. My sliding glass doors have a track that I was able to get brackets that fit over the track to hold a pole, but I had one window that I could not do that with. I thought this would be an interesting way to hang curtains without doing damage. I considered those sticky tape curtain rod holders, but I was reading a lot of bad reviews about them not holding or them taking the paint off upon removal. I figured this was the better option and it gave the room some nice aesthetics because my furniture is farmhouse white wood with black iron accents, so this blended really well with the aesthetics of the room. I know that most people who did reviews used this product as its advertised to be a room divider for privacy... So I figured this is a nice way to review using this product in a different way. I just really can't stand window blinds, as they look so commercial and industrial to me... I needed a way to make the space seem more homey. While this is working fine for me, the reality is I have white lace curtains, which don't weigh much. I don't know that I could recommend this product, even though it says it can support a bit of weight, with curtains that are too heavy. Some of that, in part, is due to the fact that one of my springs is broken so it's not very stable as it is. However, even if I was not having the issue with the spring being busted on one side, I still don't think this would be good with heavy curtains (especially if you like opening your curtains frequently). It did come with curtain hooks if you have the kind of curtains that allow you to use hooks to hang them. I do not. My curtains just slide onto the pole. If they were the type that could be put up with hooks then opening and closing them would probably be easier and maybe not as big of a deal as it is for me with the type of curtains I have. I cannot comment on longevity as I just installed it today... If anything changes I will try to remember to come back and modify this review.

This was easy to put together. It is light weight. I use it in my spare room. And I have a light weight blanket I display, hanging over it.

Does not withstand any breeze.
Color: Grey
Not sturdy, tips over easily due to a small base and ultra light weight. Instructions were not much help but it’s pretty easy to figure out without them. Material is as expected.
