CSF 2011+ BMW 1 Series M / 07-11 BMW 335i / 2009+ BMW Z4 sDrive30i/Z4 sDrive35i Automatic Transmission Only

CSF provides a high-quality product that exceeds OE standards, gets rid of the plastic end tanks, and improves cooling by 25-30%! Drop-in fitment and more efficient cooling for your street or track car.

  • Drop-in fitment to E82 135i and E90/E92 335i & 335xi automatic transmission models
  • Includes transmission cooler
  • High performance aluminum core
  • Aluminum endtanks instead of plastic
  • CSF B-Tube design
  • Designed and tested in the USA 

The E82/E90/E92 CSF Aluminum radiator is designed as a drop-in replacement to the stock system. It uses all of the factory plastic shrouding, hose connections, and mounting points. Although not a fitment concern, the thicker core will tighten tolerances, specifically between the expansion tank and accessory belt. All CSF radiators receive design and development in the USA with additional wind tunnel, vibration, thermal cycle, burst pressure, and salt spray testing done at their production facilities in Southeast Asia. During manufacturing, radiators are individually tested for leaks and receive a 30-point inspection prior to shipping. This part is a much higher level of quality than typical Chinese factory parts. CSF is an OE supplier to several manufacturers as well as providing private-label products for other radiator brands. CSF radiators have a two year warranty.

Toeless wonders. Love em!
Color: Classic Color
Not gonna lie. These are a God sent when you have an issue with your toes. I hate my toes feeling constricted so these are phenomenal! Comfortable and well worth the money. I also like my socks thin. If you wear boots or hightops, these might not be what your looking for. I do adore the different shades and you can wear them one way or the other as one side is longer. If worn one way, they are higher up the ankle and vice versa.

no toes covered
Color: Classic Color
i love these socks but there is room for improvement. The top and bottom band make indentions when i wear very long. A smooth stretchy bottom and top would be nice. i wouldn’t recommend for diabetics because of the indentions they make. They are fairly comfortable. But if not pulled on right you will walk on the band and it digs in a little. Also after awhile the top slides down and the foot part slides back. i have to keep readjusting. The material itself is soft. I am wearing and i like them but if i want more i will look for some without the elastic bands top and bottom. I dont like socks because my toes are sensitive and i am more comfortable without my toes covered. These are working for me now. In future will look for something similar.

Toes are grateful
Color: Fresh Color
I generally need more toe room in my shoes, but I don't need wider shoes. These are perfect for that. I took off one star because as I wash them , some of the stitching is coming undone. It doesn't seem to make a huge difference, however, so I still wear them. They are way too comfy to give up !

They fray and unravel after a few washings.
Color: Classic Color
They are exactly what I needed but after a few washings they started to fray and unravel. Also I was looking for black and had to buy the 4 different colors.
