CSF has over 5 decades of experience manufacturing radiators. So when it comes to keeping your engine cool and your E39 M5/540i 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.

Great so far
Size: 6 FT, Color: White
The first thing I liked about this is that the on/off switch has a mark on the ON side, unlike my last Belkin power strip, which had a switch where you couldn't tell which side was on or off. That Belkin was remote, which I really wanted, but the Belkin remote never worked reliably even from the start, so I'm happy with a surge protector without a remote but where I don't have to guess whether it's on or off if I can't see the light on the device plugged into it. Very reliable and solid performance so far and I also especially like the generous amount of space between the outlets - enough for the biggest plug without getting crowded. Also it's not heavy & clunky like some. And the 6 foot cord length works great, too - a big difference with the usual 5 foot cord. Also has 2 USB slots which I can use to charge my iPhone and USB chargers. All this at a decent price and it's not clunky or ugly. Have been using it daily all day for 3 months now with zero problems.

Very Good Purchase
Size: 10 Ft, Color: White
I bought this for my fiancee at the time who had several things to plug in, but did not have the space and would keep rotating plugs. This was able to help her organise the place better and charge multiple things at once. She absolutely loves it. It even has ports for phone chargers, which is very useful. The quality is very good as well. Strong and durable and looks good once you take care of it. Can blend in well and it looks good aesthetically.

Good for DIY projects

Good quality. All works well and seems durable enough and like that it’s easy to replace in future if damaged.
