Everyone knows that heat is the enemy of your automatic transmission. And everyone knows that higher power levels generate more transmission fluid heat. Now you can extend the life of your automatic transmission by installing the new Burger Motorsports High Capacity Trans Cooler kit. This unique plug-and-play kit replaces your factory coolant to trans fluid heat exchanger with a high-capacity fender-mounted air-to-trans fluid radiator. Includes all mounting hardware, lines, and coolant caps required for installation. Installs inside the driverside fender providing ample airflow over the large cooling core via existing openings. The result is dramatically reduced transmission temperature and extended transmission life. This kit is strongly suggested for any BMW E chassis automatic running larger than factory turbos. FEATURES AND BENEFITS Dissipates excess transmission fluid heat Reduces transmission fluid temperature Increases transmission life when racing Increases transmission oil capacity Fitment: 2006-2011 E90 Sedan 335i/335ix 2006-2013 E90 E91 Sedan/Touring 335d (M57 diesel) 2006-2011 E91 Touring 335i/335ix 2011-2013 E92 Coupe 335is 2007-2013 E92 Coupe 335i/335ix 2006-2013 E93 Convertible 335i/335ix Compatible with both RHD and LHD vehicles.

VTT now offers the ONLY easy-to-install, plug-and-play xDrive controller on the market. This device will allow you to turn off and on your xDrive capability from the driver's seat with a remote. While other options do exist such as X-Delete, or an in-dash gauge, one is a very slow process and is not viable to use as a way to do a burnout at the drag strip, and the other is a very expensive, AND very intrusive device that requires removal of most of the dash, and installing a gauge. VTT's solution takes 30 seconds to install once you gain access to the underside of the vehicle, and can be removed just as easily.
