• Turner Motorsport releases oil cooler upgrade kit for BMW 335i vehicles with the N54 twin turbo 6 cylinder - $899

      There are a lot of N54 guys that like to track their car who will likely be interested in this oil cooler upgrade from Turner Motorsport. Turner states this upgrade is just for 335i's with the N54 as it is listed as fitting the 2006-2010 E90, E92, and E93 335i including the Xi. Pricing is $899.00 for cars that have the factory oil cooler and a retrofit kit can be added for an additional $530 for cars without the factory oil cooler. Full details listed below.






      The N54 engine equipped E9X 335i is reknowned for its excellent performance and the ability to custom tune for more horsepower. Unfortunately, it is also known for oil cooling deficiencies that can reduce horsepower output and potentially compromise engine longevity, especially when driven enthusiastically or when boost is increased. To help maximize the power of your BMW, this kit adds a second oil cooler behind the kidney grills in addition to the factory oil cooler. This not only increases the cooling capacity, but more than DOUBLES it! Our kit provides the factory oil cooler with much more airflow then what is available in the fender wells.

      What is included?

      Billet aluminum oil filter housing adapter - CNC'd, anodized black
      Setrab Oil Cooler Core – simply the best brand in oil cooler cores available. Most of the competition use far inferior cores, resulting in higher temperatures and sometimes catastrophic failure. One of our customers previously had a competing oil cooler literally explode on the Nurburgring, splashing oil on the tires and track at over 150mph!
      Anodized aluminum mounting brackets + all necessary hardware
      Oil lines made from lightweight stainless braided hose, with black/nickel colored swivel fittings.
      Retrofit kit available for those who do not currently have the factory oil cooler. This includes all the OEM parts needed.


      What makes this kit superior to the rest?

      Uses a well known, highly respected, quality Setrab core
      Custom made and professionally assembled lightweight oil lines
      Retains factory oil cooler.
      Oil cooler surface area is not just increased, but more than doubled.
      Easy installation
      No hacking or cutting of brake ducts.
      Ability to add our upgrade kit that will allow you to run (2) Setrab cores for maximum cooling capacity!

      Only for cars with factory oil cooler. Cars without factory oil cooler must purchase retrofit kit.

      This item fits the following BMWs:
      2006-2010 E90 BMW 335i 335xi 335i xDrive - Sedan
      2007-2010 E92 BMW 335i 335is 335xi 335i xDrive - Coupe
      2007-2010 E93 BMW 335i - Convertible

        I added it for my street use because I didn't have a stock OC, I was one of the early 335's that didn't come with a OC :-)

        And for the street not really neccesairy to my opion....
        +1 this cooler is ok for spirited street driving, but on a road track it's just not enough. So if you plan to trsck your car, you're better off getting a proper setup from STETT or from Evolution Racewerks (my choice). Replacing the small stock oilcooler with a lager and better core is a better option than this AR Design OC.

        All oil coolers connect to the oil circuit of the car and therefor to the original oil cooler (if there is one). Therefor also the AR Design is connected to the stock oil cooler.

        Of course the AR Design oil cooler also contributes to lower oil temperatures. However, depending on your level of engine tuning and driving habits (i.e. race track or street), it may not be sufficient.

        If your car doesn't come with an Oil cooler from the factory, Ar also sells you the new Oil Filter housing with the extension to add inlet and outlet lines. Its around 500$ additional.

        Ive installed a few of these, starting with BobS and they are a nice kit. Pretty pricey for what it is, but the custom made oil line adapter (black box with AR on it) is a nice piece that took some time making.
