Producing 14 max horsepower and 27 ft lbs of torque, this radically
different Stage 2 sealed cold air intake system is engineered to let
maximum air in while keeping engine heat out. Featuring two uniquely
shaped molded intake ducts that replaces the single stock intake tract,
this intake system smoothly directs increased air flow from two
direction for improved volumetric efficiency and maximum performance.
Testing has shown intake air temperatures to drop up to 11°F cooler with
the Si intake. Complementing the dual intake tract are two aFe scoops
that channel cold air from the grill directly into the intake. The
easily accessible washable/reusable aFe air filter is enclosed in a
molded plastic housing and mounted on a oval intake tube that smoothly
supplies maximum air to your BMW's twin turbos. The full effect of this
system cannot be felt or tested on stationary dyno and can only be
fully appreciated on the wide open highway! |
