The B&M 70255 SuperCooler is universal stacked plate transmission oil cooler that is built from a very stylish polished aluminum construction, like some other B&M SuperCoolers.

The SuperCooler 70255 comes with 3/8″ barb fittings which will make for easy installation with the supplied rubber transmission hose.

Like all B&M SuperCoolers, the stacked plate design of the 70255 gives drivers an estimated 30% more transmission fluid cooling efficiency than traditional tube and fin designs while, having 15% less transmission fluid flow restriction which allows for maximum cooling. 

Based on its size and construction, the B&M 70255 would be best suited for daily driven cars and SUVs.
