This uprated intercooler has been designed for the BMW 135 E81,E82,E87,E88- 335 E90-91-92 N55 single turbo engine and N54 twin turbo engine, we have again managed to retain a very easy installation (taking less than 45 minutes with no need to remove the bumper), but also NO cutting of any bodywork. With our testing results indicating a temperature drop of 25 degrees centigrade, and of course the increase in power that you would expect from a much larger cooler charge, plus the ability to install this on your driveway at home, we have a truly excellent product.
