The B&M 70266 SuperCooler comes as a stand alone cooler, meaning there is no installation kit with hardware. Because of this, installation will be dependent on each vehicle’s application.  Since most people will commonly mount and install transmission coolers in front of the air conditioning condenser and radiator, the installation will need additional parts to accommodate this.  

The biggest thing to consider when installing this cooler is where to mount it.  Depending on your vehicle, the 1.5″ thickness may make installation a tight fit, so be sure to find a place that receives more than adequate air flow to the cooler. 

If you have a more drag race application, you can mount this cooler remotely with a cooling fan to help provide enough air flow.
