Installation: the foam/rubber hood seal does not stay in place during the installation due to the confined space in the 135i engine compartment. I have had to reposition it twice. Performance: once the car is in motion the intake scoops installed with the aFe cold air intake make a difference. acelleration seems inproved slightly. MPG highway has been increased by 3 - 5 mpg.
