Sealed Cold Air Intake for BMW N54
A well-made product that is significantly less restrictive than the stock air intake. Installation wasn't difficult, but did require working in tight areas. In addition, the aFe intake did not incorporate the harness retainers that are built into the factory intake.
1st week test
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.
