BMW F3X/F2X B58/B48 Triple-Pass Heat Exchanger w/ Rock Guard - Black. 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 #8131B comes in a Satin Black Finish for OEM+ look. It is also available in a Polished Finish (CSF #8131).

Nice oak corner shelf but check your measurements first
5 stars for the shelf, 3 stars for myself :-) This is a well-made oak corner shelf that looks great where I put it. The wood is nice quality and the construction is solid. Before you order though, do yourself a favor and check two things: 1) Make sure the size is actually big enough for what you need, and 2) Check that your corner is actually a true 90-degree angle. Turns out mine isn't perfectly square and now I'm trying to figure out how to position this thing properly. Good product overall, just wish I'd measured more carefully before ordering.

i’ve been wanting this shelf for quite some time and finally decided I’m doing it. I’m absolutely completely satisfied with the size the quality of the wood and the paint job. It’s made very well. I have to say I was surprised at how nicely sanded it was and ready to hang.

Easy install
Just installed in our bathroom. Feels solid. We have a potted plant on it now. You will want a drill bit extender to clear the shelf. I use the flexible type. Otherwise you won’t be able to get the screws in at a 90 degree angle.
